Ericsson Leads in Backhaul
In-Stat says Ericsson is the largest supplier of LTE packet backhaul equipment with 25% of
the market and the research firm suggests it will remain so through 2013. In-Stat research indicates Ericsson
will end 2011 with more than $250 million in global LTE packet backhaul equipment revenue. Other major players
are Alcatel-Lucent, Nokia Siemens Networks, Huawei, Samsung, and Cisco, adding up to 93% of the market with
ZTE, Juniper, NEC and Tellabs making up the rest.

A $25 Computer?
The Raspberry Pi, a computer board developed by a UK-based
foundation, is designed to sell for $25 in order to promote the study of computer science and related topics
in schools. The foundation is developing, manufacturing, and distributing the computer for use in teaching
computer programming to children and hopes that it will have many other applications both in the developed and
the developing world. It is about the size of a credit card and plugs into a TV or can be combined with a
touch screen making a low-cost tablet. Hardware includes a 700-MHz ARM11 processor, 128 or 256 Mbytes of
SDRAM, OpenGL ES 2.0, 1080p video decoding and composite and HDMI video output. It has USB 2.0, a SD/MMC/SDIO
memory card slot and optional 2-port USB hub and 10/100 Ethernet controller.

Heathkits Return
The company well known to veteran amateur radio operators for its
inexpensive yet capable receivers, transmitters, transceivers (remember the Benton Harbor Lunchbox?) and other
equipment has reintroduced kits after ending their production in 1992. However, they won’t be what most
readers would expect (or perhaps hope), since they are focusing on technical education curriculum, courseware,
and hardware to assist academic institutions, corporations, training centers, and 'self-study' users. They
cover PC, telecom, “core”, life science, robotics, language, “green”, and auto technology.

A Message from
Sam Benzacar
Defending Defense Communications
The fundamental role of design engineers is
to solve problems. As it pertains to filters, designers too often spend precious hours creating a set of
filter specifications that are either “overkill”, cannot be realized with a specific filter, or are physically
incompatible with the confines of the circuit or its enclosure, to name a few. Calling one of our application
engineers is not “giving up” but a way to save a lot of time and frustration -- and often money as well. We’ve
been designing and manufacturing filters for more than 20 years, and the problem you’re facing more than
likely resembles one we’ve successfully solved before.
Filters are deceptively simple devices since
after all, their job is to eliminate unwanted signals so the desired signals can pass unhindered. However,
every type of filter has unique characteristics that make it suited for particular applications and some of
these characteristics overlap. So it's possible to specify one type of filter when another type would be less
expensive, deliver equal or better performance, or be more appropriate for its environment. There are an
unlimited variety of variations on this theme, and the best way to sort them out is to talk to one of our
applications engineers.
For example, most applications can easily tolerate a VSWR of 1.5:1 but we often
receive requests for much lower values, which will drive up the cost of the filter. Upon inspection of the
actual problem at hand, we often find that a lower VSWR is simply unnecessary, saving the design engineer and
his or her company money. The same applies to many other filter specifications as well. Another common problem
is leaving the task of integrating the filter into the circuit to the end of the design cycle, even though it
is critical in determining overall performance. In this case, the time and cost required to remedy the problem
is almost invariably higher than it would've been if filtering was considered at the first stages of design.
When you’re about to design a circuit in which filtering is a key factor, please call us when you begin. The
time you save can be better spent doing what you do best.
