Anatech Electronics Receives Award from Cubic Corp.
We’re happy to announce that Anatech Electronics has received a Supplier Performance Award for 2011 from
Cubic Defense Applications. Inc., a division of Cubic Corporation. The award is presented annually by Cubic to
select suppliers that demonstrate significant effort. It recognizes the vendor’s excellent level of quality,
on-time delivery, and customer service including satisfaction, cost, and responsiveness. Anatech Electronics
has been a supplier of custom filter products to the company for many years.
LTE and Cable: Unhappy Together
Wireless communications and
cable systems may be different domains, but they share at least one thing: operation at frequencies ranging
from VHF through UHF (for cable, from 50 MHz through 750 or in some cases 860 MHz). Although the signals in
cable systems are (or are supposed to be) safely sealed off from the outside environment, there are points in
any system where signals can enter.
Studies have shown that if signals from LTE systems operating in
bands between 693 and 806 MHz enter into cable systems and even to set-top boxes, they can degrade picture
performance. The problem is caused by the particular characteristics of LTE signals and of course the
frequencies where it being deployed in the U.S. The situation is only now developing in the U.S. as LTE
adoption by consumers has been relatively slow, but as it becomes more widespread and more people upgrade to
“4G”, things could get very interesting, very fast.
GaN Gains Ground
Strategy Analytics’ report “Compound Semiconductor
Industry Review October-December 2011: Microelectronics”, states that gallium nitride (GAN) is “finally
beginning to see acceptance in commercial applications, such as CATV and wireless infrastructure.” Accelerated
activity includes growing interest in GaN-on-silicon processing to reduce cost and higher-voltage GaN
processes to increase RF power output. The primary market for GaN RF power devices has thus far been almost

Bandpass Filter Basics
As bandpass filters are by far the most common filter type, Lyn Haun and Marlene Wurms, Anatech
Electronics’ sales administrators receive more questions about their general capabilities than others. With
this in mind, they offer some specifics:
Cavity bandpass filters can achieve
bandwidths from 0.5% to 30% and interdigital types can achieve bandwidths from 10% to 100%. Operating
frequencies range from 20 MHz to 20 GHz. Power handling ability can be at least 500 W CW and in certain cases
considerably higher. Cavity filters deliver extremely high performance with low loss, and thanks to Anatech’s
many years of design experience, can be made quickly in medium to high-volume.
Ceramic bandpass filters can have center frequencies from 400 MHz to
about 6 GHz, can handle about 5 W, and have achievable 3-dB bandwidths of 2 to 20%. They're characterized by
good insertion loss performance, low cost, small size, and suitability for mass production.
Surface acoustic wave (SAW) bandpass filters from Anatech operate from
425 to 6350 MHz, handle power levels of -10 to 0 dBm, and have 3-dB bandwidths of 2 to 20%. They are very
small (typically 2 x 2 x 2 mm), very inexpensive, achieve very narrow bandwidths, and are designed for volume
LC bandpass filters operate from 100 kHz to 3000 MHz, can handle
average power of about 30 W, and can achieve bandwidths of 0.001 to 4.5%. They can achieve a very steep
transition from passband to rejection, and can be connectorized, PC board or surface mountable, and drop-in.
Insertion loss can be quite low and their frequencies can easily be shifted.
Crystal bandpass filters operate from 5 kHz to 200 MHz with power up to
3 dBm, and have 3-dB bandwidths from 0.001 to 4.5%. Crystal filters are suited for single-band applications,
have very high Q, can achieve very narrow bandwidths with sharp skirts, and are very temperature stable
considering their very narrow achievable bandwidths.

A Message from
Wavering on IMS 2012? Some Good Reasons to Go
IMS 2012 is only three months away
and some of the rumblings I hear are reminiscent of those I heard in 2007 when the symposium was in Hawaii.
Specifically, that Montreal presents additional challenges that make people question whether it’s “worth going
this year.” In Hawaii it was the cost, distance, and potential lack of traffic, and in Montreal it’s ITAR
restrictions, customs, cost, and perhaps lack of traffic as well. As this is my 20th IMS (or rather MTT), it’s
a familiar refrain. I heard this talk when the show was in St. Louis and Albuquerque as well. In every case –
even Honolulu – the results for many or perhaps most exhibitors was that their fears were not realized.
So here are some good reasons to go to IMS 2012, based on the fact that it’s the world’s largest symposium
featuring RF and microwave technology:
1. Regardless of where it is held, more people in the RF and
microwave industry go to the IMS than any other show for this industry in North America.
talking to attendees (and perhaps other vendors) about sales opportunities are the most obvious goals of
attending any trade show, other reasons are equally compelling, like face-to-face meetings with clients and
sales representatives and learning about what competitors are up to. Each one would cost more and take more
time to accomplish any other way.
3. As an international symposium, IMS attracts people from countries
all over the world, and especially Asia and Europe, which makes it a unique event.
As for Montreal:
It’s a beautiful, vibrant city with a European “feel”, and has terrific restaurants and lots of interesting
places to visit. So if you were already going or my arguments have convinced you, make sure you come see us at
