Static & Crosstalk
At the dark of the moon, when else, when the runes
said that the time was auspicious I was cleaning out the
old Astrology closet. I found under the Astrolabe covered
with the lamp black of ages ye-old crystal ball. I polished
off the lamp black with a cloth hoping that a little Ginn
would pop out, but no such luck. However, in the now
clean surface of the crystal one could see the billowing
and swirling clouds of gray and dirty white that generally
hide the future so that one can not actually figure out
what’s going on.
Having listened carefully to the
talking heads on (if you’ll excuse the
term) TV news – both bimbos and air
headed matinee idols tell me all they
know about what’s happening in Iran
concerning the Nuclear negotiations.
No. They try to tell me what they think
is happening and the conclusions I
should come to about the situation.
But, what really is happening does
shine through.
What’s happening is just what the Ayatollah
Cockamimi wants to happen: the dwarfs of the faithful are
busily singing Hi-Ho Hi-Ho while putting the finishing
touches on the Islamic bomb while the propaganda front
for the faithful at the negotiating table are emasculating
the dolts and buffoons such as our Secretary of State on
our side of the table.

September / October 2014
My crystal ball is clear. Iran will build an atomic
bomb soon.
The next step is simple. If the militants haven’t already
sent in their order to Target, they can order up a Terrorist
special – two for the price of one – Intercontinental
ballistic missile from the North Koreans or from the
French who will sell anything to anyone as long as they
don’t call any of the wine they make Champagne.
Once they have the thing, they will be in the catbird
seat and they know it. They only have to convince people
that they are crazy enough to use it. Any suicide bombing
does that handily. In fact, using it as a bomb is counter
productive. Once they blow it up, they no longer have
it and whatever it takes with it isn’t worth as much as
just having the bomb. But then they really are crazy. They
seem to believe that their mission in life is to remove as
many people who do not agree with them and damn the
torpedos full steam ahead.
And we are crazy too – remember Hiroshima and,
more importantly, remember the Maine? We didn’t figure
out that the infernal things are more valuable lurking in
silos with the sorghum than they could ever be in use,
until we sent our foes cowering because we had them and
were dumb enough to use them.
It will soon occur to all the voters in Los Angeles,
New York City and Hoboken that if Tel Aviv has an
Iron dome they need one. The politicians in DC – who
won’t have a clue about what’s going on – will in any
case feel the voters mood, count the votes and push
procurement of Over the Horizon Radars, command and
control complexes and radar guided missiles. Of course,
all will have to be EMP proof. It is, after all, a nuclear
(pronounced nuculur) defense system and everything –
including the 6-32 machine screws and bolts used – will
have to be tested to Military RFI Specs.
So, my friends, put the European Restriction of
Trade Specifications on the back shelf, forget that 3Meter
Anechoic Chamber you were going to have to buy and
haul out the old shielded chamber, mode stirrer, copperplated grounded table and RF power amplifier you’re
using to heat water for radiator steam heat of the office
complex across the street.
We’re back in the MIL-STD-461 testing business big
time.

frequency range tests. Devices claiming conformance with
the Radio and Telecommunication Terminal Equipment
Directive need to be re-evaluated by December 31, 2014
if their test reports do not reference the 1.8.1 version.
The EN 301 893 standard applies to 5GHz RLAN
equipment used in wireless local area networks and
intended to operate at 5150MHz – 5350MHz and 5470
MHz – 5725MHz frequency ranges. The 1.7.1 version
outlines the relationship between Dynamic Frequency
Selection (DFS) and uniform spreading, or adaptivity,
which allows one RLAN device to detect another. The
1.7.1 version of the standard introduces changes to testing
procedures, including RF output power, power density and
unwanted emissions, as well as adds new requirements.
Manufacturers that need compliance with EN 301 893
must re-evaluate their equipment due to these changes.
DISA to Move Swiftly on Spectrum-Related Contracts
The Defense Information System Agency’s Defense
Spectrum Organization (DISA) plans to have a “very
active year” when it comes to its spectrum-related
missions, according to a presentation given by Stuart
Timerman, director of DISA’s DSO office, at the agency’s
recent forecast to industry.
Retlif, with two locations on Long Island, as well
as New Hampshire, North Carolina, Pennsylvania and
Washington DC, is celebrating its 35th anniversary.
ETSI Updates Standards, TÜV Urges Compliance
The European Telecommunications Standards
Institute (ETSI) issued the updated versions of the EN 300
328 and EN 301 893 standards, introducing changes to
testing procedures of applicable wireless equipment. TÜV
Rheinland, a leading global certification body, strongly
encourages manufacturers of wireless devices to comply
with the updated testing and certification requirements to
ensure they can sell in the European Union following the
standard after the January 1, 2015 deadline.
The EN 300 328 standard regulates wireless
transmitters in the 2.4GHz band and affects multiple
wireless technologies, including Wi-Fi®, Bluetooth®
and ZigBee®. The latest version (1.8.1) seeks to improve
the usage and quality of data transmission within the
2.4GHz band. It introduces significant changes to
testing procedures for RF output power, power spectral
density and medium access. Changes in procedures are
also implemented in transmitter spurious emissions and

spectrum was a critical first step in the department’s long
term plans. The effort is part of a strategy from the current
U.S. administration that requires 500MHz of spectrum be
made available for commercial use by 2020.

Experts in the Field…
Cuming Microwave
Timerman highlighted the need for DSO to strike a
balance between its mission to secure spectrum for the
Department of Defense and to also determine what can
be released to commercial wireless companies. DSO is
trying to move away from its reservation-based system –
which reserves certain frequencies for military branches
until they are no longer needed – and toward a sharedspectrum system.
The strategy furthers action put forth earlier this year
by former DOD CIO Terri Takai, who says releasing

CNO Tours Navy Electromagnetic Railgun
Naval Surface Warfare Center Dahlgren Division
(NSWCDD) leaders briefed Chief of Naval Operations
(CNO) Adm. Jonathan Greenert on technologies ranging
from the electromagnetic railgun to the laser weapon
system during his recent visit. The CNO spoke to
sailors and civilian technologists about the great impact
of emerging capabilities on the current and future fleet
during an All Hands call held after his tour.
SDA Signs Pentagon Data-Sharing Agreement
A space satellite association has signed a data-sharing
agreement with the Pentagon to avoid interference with
satellite signals. The Space Data Association (SDA)
will participate in the Department of Defense’s Space
Situational Awareness Data Sharing Program.
This is the first such agreement between the Pentagon
and an entity that doesn’t operate satellites, according
to the SDA. “Under the agreement, the U.S. DoD and
SDA will now be able to formally collaborate on matters
concerning space situational awareness, including
mitigation of electromagnetic interference and radio
frequency interference,” says an SDA announcement.
The SDA was established by satellite operators to
improve satellite safety and efficiency. It is seeking the
participation of all satellite operators worldwide.

firing – described the technology as “our future surface
weapon” during the All Hands event to be available
video on-demand via the NSWCDD internal website
to the command’s 6,000 plus personnel comprised of
government civilians, contractors, and military members.
The electromagnetic railgun launcher is a long-range
weapon that fires projectiles using electricity instead of
chemical propellants. Magnetic fields created by high
electrical currents accelerate a sliding metal conductor, or
armature, between two rails to launch projectiles at 4,500
mph to 5,600 miles per hour.
NSA Certifies Harris Corp.’s Manpack
The U.S. National Security Agency (NSA) has
granted Type 1 certification for Melbourne, Florida-based
Harris Corp’s Falcon 3 RF-340M multi-channel manpack
radio. Harris is now able to field the radios for secure
communications reaching up to the top secret level of
information assurance. The company expects to make the
first delivery to the U.S. Navy this fall.
The Falcon 3 RF-340M supports all required U.S.
government wideband and narrowband waveforms,
and will deliver Mobile User Objective System satellite
“You are the test and evaluation national treasure that
makes the surface fleet more lethal and more survivable,”
Greenert told more than 400 military, government,
and contractor personnel from Naval Support Facility
Dahlgren, NSWCDD, Aegis Training and Readiness
Center, Center for Surface Combat Systems, Aegis
Ballistic Missile Defense, Joint Warfare and Analysis
Center, and the 614th Air and Space Operations Center.
The national treasure he observed included
NSWCDD facilities where real-time spectrum operations
and directed energy technologies such as the laser weapon
system and electromagnetic railgun are under a continual
state of research, development, test and evaluation.
“I am really excited – you are taking concepts and
putting it in the fleet for what is, up until now, record time,”
says Greenert, pointing out that NSWCDD scientists and
engineers are integrating the laser weapon system into
the USS Ponce (AFSB-I), an Austin-class amphibious
transport dock.
“We have to continue to turn this cycle faster and
faster,” says Greenert. “Technology gets proliferated and
other people have systems that we really don’t want them
to have. We have to figure out how to defeat and stay
ahead of that – and be where it matters, when it matters.”
The CNO – who observed an electromagnetic railgun
The radios also include an expansion slot for emerging
and unique mission needs. The extra space provides room
for potential upgrades such as higher speed wideband
networking, satellite communications, and intelligence,
surveillance and reconnaissance.

EMC NOTEBOOK
Need Multilayer Boards?
By William D. Kimmel, PE
and Daryl D. Gerke, PE
Kimmel Gerke Associates, Ltd.
In past articles, we have discussed the virtues of the
multilayer circuit boards. But this goes against the grain
of those who work in highly cost sensitive applications.
With low production volumes, piece part costs are of
little consequence – nonrecurring costs dominate. But
with high volume applications, even a penny per unit
becomes a significant factor – shave a penny from each
of 10 million units times one penny, and the savings is
$100,000.
High production volumes dominate in automobile
and consumer goods. The automobile has hundreds of
special circuit boards scattered all over the vehicle, but
you’ll have to look hard to find a multilayer board –
actually, single sided boards are common. So what are the
determining factors in demanding multiple layers?
The Magic in Multilayer Boards
The ground plane in multilayer boards performs it’s
magic by providing low impedance ground return paths
and by facilitating small loop areas.
The result is two-fold – low inductance current paths
and low magnetic field coupling. The principle result of
the low impedance path is reduced voltage drop along the
path, especially at high frequencies.
Ground impedance of a plane is far lower than that
of a circuit board trace. Using our rule-of-thumb that
inductance of a wire or trace is approximately 8nH/cm, we
compute the impedance at 100MHz to be approximately 5
ohms. The impedance of a ground plane is approximately
that of one square which, at 100MHz is approximately 10
milliohms – 1/1000th that of even a short trace. This is an
amount that is impossible to ignore.
As an example, figure 1 shows what happens when
an interference current travels along a ground path. Let’s
assume we have an ESD current of 1 amp (much less than
a full ESD hit). This will drop approximately 80 volts
along a one cm ground trace, an amount unacceptable in
virtually every case. But the voltage drop along the ground
plane will be about 10 millivolt, acceptable in almost all
Page 16
Figure 1. Ground Bounce in Inductive Trace
cases.
This ground impedance creates a similar situation,
where voltage in a clocked signal return path creates onboard common mode voltage which, left unchecked, will
cause currents to take an alternate path along ground to
the outside world. Yes, the amount of current is small,
but it doesn’t take many microamps to create an emission
issue.
The second aspect is reduction of loop area (figure 2).
Traces routed close to the ground return are automatically
small loop area. Faraday’s law says that magnetic field
coupling is proportional to the loop area, Small loop areas
minimize coupling to and from the loop. Thus, magnetic
fields crosstalk to adjacent traces and nearby off-board
loops. It is to your benefit to keep loop areas to a minimum,
which is greatly facilitated with a ground plane, but are
very dificult to minimize without an adjacent ground
plane.
Ultimately, the goal is to reduce ground bounce. This
can be done in two ways – reducing ground impedance
and reducing current on ground.
Let’s start with reducing ground impedance. While
we don’t have a ground plane, per se, we do have a
copper layer, some of which may be allocated for ground
purposes. Anything we can do to widen the ground path,
shorten the path length, and run the signal trace over the
ground will reduce the path inductance.
Since we don’t have unlimited real estate, we need
to be smart about allocating more copper for the critical
paths. So the first order of business is to identify the key
paths:
For immunity, the key lines are input signal lines,
which will need to be protected by filtering or transient
protection. This means we need to have a low impedance
path from signal to signal ground. A common filter
includes a capacitor in this path – accordingly we need
to minimize the inductance along the way. If you can put
the capacitor immediately between the signal pin and
chip ground, you don’t need to allocate any copper at all,
This is easy to do when the ground pin is adjacent to the
signal pin, but difficult if you are filtering a number of
signal pins. In such a case, your best choice is to keep
the path length from signal to ground as low as possible,
then fatten up the trace to keep series inductance as low as
possible.
For emissions, there are two possibilities – emissions
from the signal pins and emissions on ground pins.
Dominant signal lines are output pins, especially those
carrying direct periodic clock or bus energy. Clock noise
on the power rails will inevitably show up on output
pins, no matter what the signal does. In such cases, low
impedance filter path from signal output pin to chip
ground is mandatory, using the same considerations as
with the input pins cited above. Just to note that hanging
a capacitor from low impedance driver to ground is not
adviseable – put some series impedance (resistance or
ferrite) immediately at the output pin.
The other possibility is common mode, which
is more general in nature. At the circuit board level,
common mode interference is primarily caused by ground
Figure 2. Loop Areas in Mulitlayer and Two-Layer Boards
So What To Do?
EMI problems mostly involves wires entering or
leaving the circuit board, including signal lines, ground
lines and power lines.

impedance, specifically that involving the return path of
periodic signal lines, notably clock and data buses. Here it
is imperative that the key path lengths be kept as short as
possible, and that the ground path be continuously under
the signal path and as wide as possible. Note that common
mode noise goes out the ground path – signal filtering is
irrelevent – the ground currents must be minimized, and
the residual blocked with the use of ground impedance,
usually involving common mode chokes.
Considering these possibilities, figure 3 shows the key
issues in two layer board design, which involve keeping
loop areas small, maximizing ground area, and selectively
filtering key signals and power paths.
memory and I/O. Typically, there will be a shortage of
ground pins, generallly no more than one per side. We
allocate a copper patch under the foodprint of the chip,
ensuring low ground impedance no matter what pins are
involved. Each pin entering or leaving the board is at
risk – power, signal in, signal out and ground. A T-filter
is employed for bi-directional signal paths – allowing for
the fact that input pins are most vulnerable to external
interference and output pins are most vulnerable for
emissions. Depending on the need, we may want to insert
series impedance in the ground wires entering and leaving
the board, as well.
Summary
The key EMI problems associated with two sided
boards can be minimized with careful attention to ground
impedance. Keep critical signal paths as short as possible,
with a continuous fat return path underneath. Keep
inductance in filter capacitors as low by keeping leads as
short as possible. Keep as much copper on the board as
possible to facilitate low ground impedance.

OVERVIEW
With trillions of dollars having been invested in electricity, it’s no secret that it’s a key mechanism for
carrying out most of our operations and day-to-day activities. However, wires and batteries (the traditional tools
for enabling electricity transfer) are cumbersome, and as the number of devices continues to increase,
managing wires and identifying outlets will only become more difficult. Kaynam Hedayat of WiTricity will
explain how wireless electricity addresses these challenges by providing a seamless, easy way to charge.

Introducing The Only 4000 Watt CW, 80-1000 MHz Amplifier Of Its Kind
Usually, we talk about all the features that make our amplifiers superior to
all the other amps out there, but this time we can’t. There simply is no other Class A
4000 watt amplifier that covers the 80-1000 MHz frequency range. Not only is
AR’s Model 4000W1000B in a class by itself, it’s now approximately 1/3rd the size
of our previous model.
When you specify this 4000 watt amplifier you’re getting a tough, durable
and completely reliable product that delivers all the power promised time after time.
AR amplifiers perform beyond expectations, beyond the norm, and beyond
the capabilities of ordinary amplifiers. As the industry leader for over 45 years,
AR products are supported by a technical and customer support network that is second
to none, and one you can rely upon to solve any problems or satisfy any requirements
that you may encounter.
So when you buy an AR 4000 watt, 80-1000 MHz amplifier or any low power unit,
you can’t go wrong.
