60 GHz Wi-Fi Just
Around the Corner?
Scott L. Spencer
I read with considerable interest a recent announcement from industrial giant Samsung Electronics concerning the development of its IEEE 802.11ad 60 GHz
Wi-Fi technologies. Experience tells us that there are
significant hurdles which have to be overcome to make
60 GHz Wi-Fi commercially viable. Signals at these
frequencies travel by line-of-sight, have weak penetration properties, and are susceptible to path loss.
Certain gasses such as oxygen, water vapor, carbon
dioxide and nitrogen can attenuate signals at these frequencies putting
them at the mercy of meteorological and atmospheric conditions. The
result can be poor signal and data performance. Samsung claims that by
leveraging their capabilities in millimeter-wave circuit design, high performance modem technologies, and by developing wide-coverage beamforming antennas, they are able to effectively achieve high quality, commercially viable 60 GHz Wi-Fi technology.
Samsung says it has also enhanced the overall signal quality by
developing the world’s first micro beam-forming control technology that
optimizes the communications module in less than 1/3,000 seconds.
While beam-forming has been around for decades and is already being
used with current standards Samsung seems to have come up with a
workable way to use it reliably at 5 mm wavelengths. The technology will
allow data transmission of up to 4.6 Gbps, or 575 MB per second. This
would be about five times faster than the current Wi-Fi speeds for consumer electronics devices, which stands at around 866 Mbps per second,
or 108MB per second.
Like the 2.4 GHz and 5 GHz spectrum, the 60 GHz spectrum is unlicensed across the globe. Samsung plans to apply this new technology to
a wide range of products.
“Samsung prides itself at being of the forefront of technology innovation, and is delighted to have overcome the barriers to the commercialization of 60 GHz millimeter-wave band Wi-Fi technology,” said Paul
Templeton, General Manager, Enterprise Networks. “This breakthrough
has opened the door to exciting possibilities for Samsung’s next-generation devices, and has also changed the face of the future development of
Wi-Fi technology, promising innovations that were not previously within
An Emerging Trend but Not Necessarily New
The 60 GHz Wi-Fi standard is not a new idea and it is not just
Samsung’s idea. The Wi-Fi Alliance, a global non-profit industry associa-
tion, announced the 802.11ad ‘WiGig’
brand late last year to take advantage of the 60 GHz frequency band.
Nonetheless, Samsung’s announcement offers great promise for to cellular providers who have experienced a logjam created by the
expanding use of cellular wireless
Internet devices. Providers are
increasingly offloading their data
traffic onto Wi-Fi to alleviate the
burden. A Cisco Systems study has
predicted that 52% of all worldwide
mobile traffic will be offloaded to
Wi-Fi by 2018. In the United States
that number jumps to 64%. If the
study is correct the time is rapidly
approaching when Wi-Fi will no longer be considered a ‘secondary’ network but the primary one. The swift
increase in mobile data traffic could
result in new and unlikely partnerships and spawn mergers that previously seemed inconceivable.
ever delivered a PowerPoint presentation to a group connecting the
various “dongles” to your laptop or
tablet can be time consuming and
distracting to your audience whether it’s VGA, HDMI, DP, miniDP or
any of the others. 60 GHZ Wi-Fi has
the potential to eliminate the cablesnot only in the office environment
but for home AV as well.
We could see products with the
new Wi-Fi capabilities as early as
next year. It will likely be a long
time before they are as ubiquitous
as the 2.4GHz and 5GHz devices we
use today, but Samsung’s announcement is a harbinger of good things to
Not So Fast
It’s important to bear in mind
that this 60 GHz Wi-Fi technology
relates to streaming data locally.
Streaming video, file downloading,
web browsing is still dependent on
the quality and speed of your internet connection. These are the things
most of use our Wi-Fi connections to
accomplish. Like the new 4K televisions other technologies will have to
“catch-up” before its full potential
can be realized.
Seamless Connectivity
Samsung is also deeply involved
with the Internet of Things through
the Samsung Smart Home initiative,
so expect to see faster, more responsive interoperability between inhome appliances. Samsung says it
will use the new 60 GHz technology
in a variety of products, including
audio visual, medical devices, and
telecommunications equipment. The
new standard will be a big part of its
push into the automated “smarthome/office” market. If you have

Wireless Testing Solution Providers
Thrive by Offering End-to-End
Network equipment manufacturers and network operators face an uphill task in adequately testing and monitoring network infrastructure in a cost-competitive environment. This is mainly due to the surge in digital data
and proliferation of virtualization, software-defined network (SDN) and network functions and virtualization
(NFV). The heterogeneity and complexity of the market
has compelled test solution providers to develop innovative
tools that efficiently test and provide network visibility
without an increase in the OPEX.
New analysis from Frost & Sullivan finds that the
market earned revenues of $1.33 billion in 2014 and
estimates this to reach $2.66 billion in 2021.
“Fueled by rapid penetration of smart devices as well as
the Internet of Things, growth in Big Data caught network equipment manufacturers and network operators by surprise,” said Frost & Sullivan Measurement &
Instrumentation Research Associate Rohan Joy Thomas.
“As legacy monitoring systems are proving inadequate,
there is likely to be a major overhaul in the type of
equipment used for monitoring and analyzing data
in real time, as well as in the integration of meaningful
data back into data centers.”
The rise in the number of third-party service providers
and the heterogeneity of the network infrastructure – comprising 2G, 3G, 4G and voice over long term evolution
(VoLTE) deployments – also make a solid case for novel
solutions. End-to-end solutions, consisting of both legacybased systems as well as contemporary network monitoring systems, are the need of the hour.
While end users benefit from the presence of wellestablished market participants that deliver a thorough
range of solutions, their presence creates high entry barriers for new market participants. To gain a foothold, emerging players need to market unique and differentiated
product portfolios.

Opposing Regional Trends will
Dictate Defense Spending Outlook
Global spending on defense will grow to over $2.1
trillion by 2023 over the 2013 to 2023 ten-year period
with the Asia-Pacific region showing the fastest
growth. The Strategy Analytics Advanced Defense
Systems (ADS) service report, “Opposing Trends in North
America and Asia-Pac will Dictate Defense Spending
Outlook,” predicts that while budgetary challenges remain
at the forefront of global defense spending, regional geopolitical factors will translate to increases across all regions.
10 High Frequency Electronics
Strategy Analytics’ projections for global defense
spending are derived from analyzing and assessing 84
countries collectively accounting for around 98% of
total global defense expenditure.
n Spending in Europe will remain flat as an overall
proportion of global expenditure reflecting a mix of priorities. While budgets in Western Europe are expected to
remain flat to stable, this will be offset by increased spending by Nordic and Eastern European countries.
n Both the CALA and MEA regions will also see growth,
collectively accounting for 16% of global defense spending
in 2023.
“North American spending will be dictated by US budgets and the impact of sequestration. We expect supplementary add-ons to US spending to smooth out the overall
impact of sequestration reducing the net cuts through 2019
before flattening out and showing a moderate increase over
2022 to 2023,” observed Eric Higham, North American
Director for ADS.

Military Outlook for GaAs Devices to
Outstrip Commercial Market Growth
Growing momentum behind the use of solid-state technologies in radar, electronic warfare, communications and
other systems will drive increased demand for GaAs
devices through 2018. The Strategy Analytics Advanced
Defense Systems (ADS) service report, “GaAs Industry
Outlook 2013-2018,” and associated spreadsheet model
predicts that GaAs device demand from the defense
sector will grow at almost three times the growth
rate for the commercial GaAs device market.
Some of the key findings from the report:
n The military GaAs device market will grow at a
CAGR (compound annual growth rate) of nearly 13%,
exceeding over half a billion dollars by 2018.
n While GaAs devices are used in Electronic Warfare
(EW) and smart munitions applications, the communications and radar applications will drive the bulk of demand.
n The largest usage of GaAs devices will continue
to come from radar applications which will account for
over 60% the merchant GaAs military market revenue.
“Changing battlefield philosophies including a shift
toward more asymmetric conflicts will place a premium on
electronic capabilities,” noted Asif Anwar, Director of the
ADS service. “GaAs devices have traditionally played an
important role in defense applications and future system
requirements are driving increasing demand for solid-state
solutions which will propel demand for GaAs devices as
well as other compound semiconductor technologies.”

weapons and cybersecurity systems has been transitioned to military partners under DARPA’s Integrity
and Reliability of Integrated Circuits (IRIS) program.
Researchers with SRI International, an IRIS performer, announced they have provided Advanced Scanning

Surface Warfare Center (NSWC) in Crane, Indiana,
where it will join an arsenal of laboratory equipment used
to ensure the integrity of microelectronics.
The ASOM technology housed at NSWC Crane will help
engineers provide forensic analysis of microelectronics, including integrated circuits (IC) confiscated by law
enforcement officials. The ASOM operates by scanning IC using an extremely narrow infrared laser
beam, which probes microelectronic circuits at nanometer levels, revealing information about chip construction
as well as the function of circuits at the transistor level.
“The Advanced Scanning Optical Microscope—one of

Optical micrograph of III-V lasers monolithically integrated on silicon substrates.
DARPA’s Electronic-Photonic Heterogeneous Integration
(E-PHI) program has successfully integrated billions
of light-emitting dots on silicon to create an efficient
silicon-based laser. The breakthrough, achieved by
researchers working on the program at the University
of California, Santa Barbara (UCSB), will enable the
production of inexpensive and robust microsystems that
exceed the performance capabilities of current technologies.
Defense systems, such as radar, communications, imaging
and sensing payloads rely on a wide variety of microsystems devices. These diverse devices typically require particular substrates or base materials and different processing technologies specific to each application, preventing
the integration of such devices into a single fabrication
process. Integration of these technologies, historically, has
required combining one microchip with another, which
introduces significant bandwidth and latency limitations
as compared to microsystems integrated on a single chip.
DARPA started the E-PHI program in 2011 with a
goal of integrating chip-scale photonic microsystems with high-speed electronics directly on a single silicon microchip. Although many photonic components can now be fabricated directly on silicon, realizing
an efficient laser source on silicon has proven to be very
difficult. Traditional approaches to adding lasers – and
by extension, gain material – on-chip include separately
fabricating lasers on expensive wafers, which then have
to be bonded onto silicon chips. This conventional bonding
process requires extreme precision and time that drives
up the cost of production.

Optimizing a Coaxial Connector
to Microstrip Transition
This application note illustrates the use of the Analyst 3D finite element method (FEM) electromagnetic (EM) simulator, fully integrated
within the NI AWR Design Environment platform, for optimizing (matching of) a coaxial connector microstrip transition. Analyst simplifies design
by keeping all design data within one project file, including connectors,
bonded packages, housing, or any other arbitrary 3D objects. Various transition models from different connectors to different board substrates can likewise be stored as
a library and conveniently used in any subsequent circuit design.
Using Analyst 3D to
optimize a coaxial
connector to microstrip
The Design
In the schematic (parent document), a printed circuit board has been drawn with the signal
trace. The 3D connector that is designed for 20 mil substrates is, technically speaking, a sub
model (or child) of the parent document, making the design hierarchical. The connector model
allows for the placement of a port on the coaxial cable end of the connector (input port) and for
the other port to be defined as a regular wave port at the end of the microstrip (output port).
The reference plane of the output port is moved just after the connector.
It is important to note that when comparing measurement results to simulated ones, the
transition from the measurement hardware’s coaxial cable to the signal trace of the device
under test (DUT), as shown in Figure 1, is commonly assumed to be ideal. In reality, however,
this ideal condition can result in data mismatch (simulation data =/ measurements) at higher

coaxial cable to the signal trace of the DUT.

Figure 3 • The S11 in of the transition in this coax-to-microstrip graph
reveals that the inherent matching is good only up to about 2 GHz.
This ideal assumption is implicitly made as soon as the simulation input
and output ports are placed on the trace. In this case it is the microstrip or
coplanar waveguide, as shown in Figure 2. Here the simulation port is
directly placed on the microstrip, thereby neglecting the discontinuity represented by the connector in Figure 1 and thus systematically distorting the
simulated versus measured results.
While there are multiple methods that can be used to ensure that the
transition has as little reflection as possible, using Analyst for the method
described in this application note enables designers to treat the transition
parasitics in an analytic fashion, moving away from the ideal assumption
towards a more realistic approach.
In Figure 3, the S11 of the transition reveals that the inherent matching
is satisfactory but only up to about 2 GHz. Given that the target design

case) and thus optimization of the transition is
warranted, not only to address the loss of
energy, but also to account for mismatch.
Optimization Strategy
The transition model can be optimized in a
schematic within NI AWR Design Environment
by using ‘EM document’ as a regular sub
model. By inserting a series-L parallel-C
matching circuit, the transition can be readily
optimized at 10 GHz. In microstrip, a series-L
can be realized by a narrow segment of strip,
while a parallel-C can be realized by a wide
strip segment. Within NI AWR Design
Environment software, it is straightforward to
optimize the required strip dimensions, as
shown in Figures 4 and 5.

the optimized transition at 10 GHz.
26 High Frequency Electronics
To summarize, this simple matching circuit/optimization exercise provides signal
transmission from the coax cable into the
microstrip with less than -20 dB reflection at
10 GHz (the target design frequency). The
matching bandwidth is now about 2 GHz and
is easily and reliably optimized with the
resulting EM modeled connector using conventional circuit models. Finally, a full 3D
EM verified solution is readily available with
the optimized geometry as well.
The use of Analyst for the EM simulation
provided a more realistic, reliable approach
to achieving design success in this application. Analyst 3D FEM technology within NI
AWR Design Environment enables designers
to move smoothly from circuit concept to full
3D EM verification with a single mouse click.

Optimizing Averaging for Better
Power Measurements
By Orwill Hawkins
One of the most often asked questions from power sensors users is what should I set my
power sensor’s averaging to? This question is asked by new power sensor users as well as
advanced users, often from engineers creating test systems with programmatic remote control. This paper will explain the reasoning behind averagAnswering the question:
ing, what is occurring in the sensor and how to best determine the requireWhat should I set my
ments in your situation.
power sensor’s averaging
What is averaging? Modern power sensors use a detector circuit coupled
to analog to digital converters to measure signal power. The sample conversion occurs at a very
rapid pace, often over a million times per second on any input signal including CW signals. This
rapid conversion of the signal makes possible the measurement of very short variations in power
level including noise in high sensitivity sensors such as LadyBug’s LB480A. Most modern power
sensors whether they be thermal, diode or logger-based will have a fast analog to digital converter system.
To manage the measurements and create a stable result, individual digital converted values are averaged together as
selected by the user. This is what we call
averaging. In some instances averaging is
referred to as integration or integration
time, for the purposes of this paper we will
use the term averaging. Averaging may be
referred to in units of time or the number of
samples. We generally refer to averages in
terms of the number samples.
The samples may already have been preaveraged by analog or digital methods. For
example, in a diode detector circuit the
diodes will drive a capacitor, this capacitor
will establish the initial averaging. In many Figure 1 • Set Averaging.
test system environments wherein measurement speed is very important, users may
choose set averaging as low as possible, particularly if the signal is at a relatively high level. A
power sensor user can set a LadyBug LB479A or LB480A to continuously collect over 2,000 preaveraged measurements per second. Pre-averaging in these sensors is 124 samples for each of
the 2,000 measurements. In this case, the downside can be measurement variation due to noise
or other signal related factors on low level signals. Conversely, a power sensor user replacing a
traditional thermal sensor and desiring a very stable measurement on a CW signal, may choose
to set averaging to a very long period of time. Long averaging periods are often used to average
out noise on low level.

will net many, many results and may help put noise
sources into perspective. Noise reduction in passive components is a science in itself. As a result of noise power,
with no user signal present, there can be measurable
power that may interfere with a low level signal when
applied. Figure #2 depicts a power sensor input system
with internal noise sources indicated.
Quality power sensors generally have a very wide
dynamic range and may be capable of measuring signal
levels down to the sensors noise floor. To make low level
measurements, all noise sources must be mitigated.
Averaging is one tool used to do this. Because noise is
random in its nature, averaging the noise samples and
processing the information can eventually result in a
stable, meaningful measurement on extremely low level
Noise can be average to a single value; however changing conditions may cause this stable value to shift. For
example if the temperature is changed, the level of noise
generated by electronic components will also change. With
LadyBug Sensors, this is largely managed for you by our
patented No-Zero system. These patents allow for management of zero offset and eliminate the need to zero the
sensor prior to use. Further, LadyBug sensors account for
thermal change making it unnecessary to stop measuring
to zero. This is a significant advantage; many sensors with
built in zero circuitry must stop making measurements to
perform zero function. This can often take 10-20 seconds.
Averaging Power from Modulated Signals
Signal variation is an important consideration when
setting averaging for a stable, accurate average power
measurement. Signal power can vary for various intentional and un-intentional reasons. Today, there are many
modulation schemes that must be tested in manufacturing, laboratory and in the field. With enough averaging,
any modulated signal can be smoothed into a stable
value. Known factors such as pulse repetition rate can be

applied to the stable average power to achieve desired
In the example below, a pulse stream is depicted with
a repetition rate of 10ms and a pulse width of 1ms. The
signal, shown in Figure #3 with an averaging time of 5ms
would result in an inaccurate average power measurement. The power meter will display erroneous data as the
5ms averaged measurements are reported.
In this case averaging of 100 times the 10ms repetition
rate (1 second of averaging) would result in a fairly small
error. If higher accuracy is desired, averaging should be
increased further. Averaging of several seconds may be
needed. LadyBug sensors can also be set to employ
extended averaging to optimize power measurements.
Extended averaging uses exponential averaging along
with normal averaging and can be used to stabilize the
measurement and provide fast averaged measurement
Time or Number of Averages
LadyBug sensors continuously collect data. Data is collected at over 2,000 measurements per second. Each measurement is considered one average. It is easy to convert
from the number of averages to averaging time using the
formula below.
Averaging time=Number of averages/2,000 or
Number of averages=Averaging time * 2,000
Therefore setting averages to 2,000 will result in about
1 second of averaging on a LadyBug sensor. In reality,
each of the 2,000 measurements per second is pre-averaged by the sensor’s analog front end, digital processing
plus any digital filters that the user may engage.

In the case of a pulse profiling sensor with trace measurement capability such as the LB480A or LB680A, the

In Figure #4, the attenuated pulsed signal with no
averaging applied is buried in the noise and the pulses are
nearly indiscriminable.
In Figure #5; the same signal, the sensor is set to
apply 20 averages and the signal begins to appear.

information. LadyBug’s LB480A

way to visualize the application and results of averaging
for noise reduction. The following example was done with

11us, and 50db of attenuation, was applied to the sensor
and various averaging scenarios implemented.

Common Mode Filter Chokes for
High Speed Data Interfaces
By Coilcraft
High speed data interfaces like USB, HDMI, Wi-Fi, IEEE1394/FireWire
and LVDS require careful consideration to ensure reliable communication
free of disruptive EMI. Of the many tools at the designer’s disposal like trace
routing, termination and component placement, the common mode filter
choke remains one of the most powerful. For the variety of signal sizes, thermal variations and spectral density in high speed communications, the common mode filter choke
is an effective and widely used interface circuit component. Common mode chokes help maintain
the integrity of high speed communications and may be necessary for conformance with FCC and
international regulatory standards. FCC CFR 47 applies generally to radio frequency devices (Part
15) and includes particular requirements for Industrial, Scientific and Medical Equipment (Part
18). In addition to required standards conformance there may be other application-specific requirements. For example, major auto makers maintain their own EMI requirements for vehicles.
Considerations for
selecting a common
mode choke.
Common Mode Choke Selection
The optimal common mode choke for a particular application depends on many factors.
The first step in selecting a common mode choke is to select only those that will not adversely
attenuate the differential signal. The communication standard determines the data rate and
therefore the required bandwidth for the differential mode performance.
Data rates

Table 1 • Typical data rates.
It is relatively straightforward to select a part with low differential mode attenuation up to
the appropriate data rate. As seen in Figure 1, the differential mode attenuation does not rolloff
until above 1 GHz, making the 0603USB parts suitable for typical USB 3.0 data rates.
Even though the differential mode performance is straightforward, and the requirement is
predictable for a given data rate, the real focus should be on determining the required common
mode performance. The amount of filtering required also depends on the data rate, but is harder
to predict because of all the possible physical aspects of the application that may affect the
amount of undesirable EMI generated. Design considerations such as impedance matching, connector pin impedance, trace widths and shielding may impact the final design.
When a challenge does arise, it is important to identify the right solution. One easy choice is
to identify application-specific chokes; that is, filter chokes that have been designed with specific

like current rating and DC resistance as well as overall
size. Then common mode and differential mode curves are
presented for the frequency range specified, allowing a
quick and meaningful comparison of the options.
Alternatively, if a specific inductance value has already been identified, the database can be searched
from that input. The result is then
displayed as a sortable list, handy to
find a part with all the needed features.

Book Review
Fundamentals of Vector Network Analysis

Sixth edition 2014
ISBN 978-3-939837-06-0
Review by Tom Perkins, HFE Senior Technical
Wow, this one is really exemplary! The
first thing noticed is the high quality of the
glossy paper stock used, the very high quality graphics and photographs, and the
superb organization of the text.
This book explains just about everything related to Vector Network Analyzers
(VNAs). The author accurately states that
the device is the most complex and versatile
instrument in the field of RF engineering.
He also astutely observes that when combined with one or more antennas, it becomes
a radar system.
Many questions that the reader might
have been “afraid to ask” are succinctly presented including things like what different
connectors look like and their compatibility.
For someone in the lab, they will learn more quickly how
to make accurate measurements. A tech writer creating
test procedures will be able to define procedures with
less ambiguity.
60 High Frequency Electronics
Upon careful examination of all chapters, undoubtedly almost any reader will appreciate the broader capability of the instrument than may have been previously
perceived. Considering the size of the equipment investment, along with time and
bench space that may be saved, the book
quickly will pay for itself.
First, the instrument itself and its capability are explained in detail. Next, general
S-parameter measurement procedures are
outlined. Measurement accuracy and calibration is explained in detail, followed by
many types of linear, time-domain, nonlinear, and mixer measurements. Finally,
antenna and radar cross section measurement techniques are discussed—a nice surprise!
The book is a nice balance between theory and practical hardware visuals with
examples. Some of the publisher’s instruments are
described in the last pages of the book—not an unreasonable hype of some good equipment.
