IN MY OPINION
Two Sides of the DoD Coin: Budgets Slashed, UAV Market Soars

By Fred Ortiz, President
dB Control


As we embark on a new year, imminent cuts to the U.S. Department of Defense (DoD) budget are top of mind for those of us in the military electronics market. At a recent House Armed Services Committee hearing, the nation’s military chiefs cited a $600 billion defense cut as “catastrophic to the military” and having a “severe and irreversible impact.”

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...

T3 Mixer Family

Intermodulation distortion (IMD) suppression is a critical issue in modern military and commercial RF/microwave systems. Pressed by the demands imposed by distortion-sensitive digital modulation formats, modern systems routinely specify linearity requirements that are impossible to attain using conventional approaches. To meet these challenges, the company has introduced the Two-Tone-Terminator (T3) mixer family. The T3 mixer has the following properties: low conversion loss and extremely wide bandwidth; unparalleled IMD suppression; high 1 dB compression point; LO drive level flexibility; and a square-wave LO drive. Two key breakthroughs enable the T3 mixer: the use of near-ideal commutating behavior and the employment of internal feedback circuitry.

High-Power Amplifier Offers Broadband Performance for Comms Jamming Apps
The new Empower 2074 solid-state high-power amplifier is capable of delivering a power output of 1000W over the frequency range of 100 to 500 MHz, making it ideal for jamming signals in military communications wavebands. Primarily aimed at EW training applications, the amplifier is lightweight and compact enough to fit in any standard 19” rack and would typically be mounted inside an aircraft. This ruggedly constructed amplifier consists of two modules – one for the RF power section and the other accommodating the main power supply and control circuits. It features built-in monitoring and protection functions and also incorporates a forced air cooling system.
