FCC Unleashes Backhaul Spectrum
The FCC has voted unanimously to free up a maximum of 650 MHz of spectrum for mobile wireless backhaul and
make it easier and more cost effective for wireless companies to use point-to-point microwave links to deliver
their service, particularly in rural areas.
Rosy Picture for Point-To-Point
The Dell' Oro Group’s 5-Year
Forecast Report on the microwave transmission industry projects that the point-to-point microwave transmission
market will exceed $6 billion by 2015. The report states that demand for mobile backhaul is expected to
trigger an increase in radio transceiver shipments, which is expected to reach nearly 3 million units.

A Message from Sam Benzacar
The Invasion of Digital Devices
It should really be no surprise to anyone that defense system manufacturers are attempting to remove as
much analog (read: microwave) content in the receive chain as they can between the antenna and the point at
which the signal is downconverted to baseband. Testament to this fact are the comments from a large number of
manufacturers quoted in the July issue of the Journal of Electronic Defense. There are enormous advantages to
working with a signal in the digital domain: extraordinary amounts of signal processing can be performed in
near real-time, the systems themselves can be smaller, and the tweaky nature of analog components can be
dispensed with, to name a few.
While this is an enviable goal, and one that is all but a necessity
considering the complexity and increasing density of threats, the fact remains that with the current state of
the art in analog to digital converters, only a single stage of those analog components can actually be
eliminated. That's because it's currently possible to sample only at an input frequency of about 2 GHz. Above
that frequency, the traditional mixing stages, low noise amplifiers, and filters that form downconversion
schemes are still required and are likely to be for a very long time. Converters, unlike microprocessors,
don't follow Moore's Law and massive enhancements are years in coming. On the transmit side, the picture is
even brighter for microwave manufacturers because high-power components cannot be replicated by digital
techniques, and until someone figures out how to generate RF power with a digital device, RF power
transmission will remain firmly in the microwave camp. The signal may be digital but the devices that transmit
it will continue to be analog.
As interference to defense systems is on the increase, the need for filters is also virtually assured. More
and more frequently, we receive requests to mitigate interference issues
in systems installed in the field. This can result from the fact that interference issues were not correctly
addressed when a system was installed or new interference has popped up since then. For more than 20 years,
we've been solving problems like these with high-performance filters that have extremely high rejection, high
power handling ability, and exceptional ruggedness.
