 Small is Bigger, Better and More Innovative?
By Bob Pinato,
ICCS, LLC.
Here we are four years into the worldwide economic crisis, which to date has yielded one of the worst financial downturns the western world has seen since the 1930s, and still there is debate whether or not we are facing a long anticipated election year upturn. Military budgets are being scrutinized carefully for the proper balance between the costs for national security, secure jobs in key congressional districts, pet pork programs and the cost of the war efforts.

LightSquared:
The Show’s Over
…Or Should Be
By Barry Manz
There are a lot of very technically astute people at the Federal Communications Commission. Many have decades of experience at every level of RF and microwave technology. How then might LightSquared’s proposal for a satellite/terrestrial LTE network have ever gotten past its first hurdle? Even a cursory inspection of the plan, in which the company's network would operate extremely close to GPS frequencies at L-band, makes interference to GPS devices almost a certainty. Read More...

 Lock-In Amplifier (LIA)
The fastest commercial LIA ever commercially produced, the UHFLI (Ultra-High Frequency Lock-in Amplifier) from Zurich Instruments performs measurements as high as 600 MHz – three times faster than any other current LIAs.
BNC Scientific
 Coaxial Power Splitter/Combiner
The ZC9PD-172+ is a coaxial power splitter/combiner that is usable from 1100 to 1700 MHz. Features include low insertion loss (0.6 dB typ.), high isolation (18 dB typ.), and excellent output VSWR (1.2:1 typ.). Operating temperature range is -55 to +100ºC.

 WG-Series
This waveguide filter was designed to cover a narrow frequency band in order to facilitate point-to-point routing of data over the network. Units maintain low loss and high rejection. This unit covers narrow frequency bands above both 18 and 26.5 GHz.
RLC Electronics
 Three-Section Narrowband Cavity Filter
From the new CS series, this 3-section narrowband cavity filter has a center frequency of 1521.5 MHz with an equiripple bandwidth of 2.6 MHz minimum, yielding an insertion loss of 3.0 dB maximum. VSWR is less than 1.5:1 over the passband.
