IN MY OPINION
Mobility, Electronics Appetite: Loosen Your Belt and Call Jenny Craig
By Doug Bathauer CEO, Integral Technologies
Everywhere you turn you hear medical experts, fitness personalities and even the First Lady are weighing in to curb the growing American obesity epidemic. Our insatiable appetites and inclination to consume in excess are also having an impact on the transportation industry as well. Our propensity to over-indulge, carries a heavy toll, from our waistline to the highways. Read More...

Pentek
xxx Up/Down Converter
The LO-MIX is said to be the smallest up/down converter in the world, with frequencies from 2 to 45 GHz and power up to +25 dBm. Internally matched to save time, space and cost. Free-running, internal or external reference models are available.
Microwave Dynamics
xxx Microwave Power Module
The dB-4118 is a Microwave Power Module (MPM) operating in the frequency range of 6 to 18 GHz. This MPM is a power amplifier that provides 75/100W CW RF output power. The RF signal path consists of a solid state amplifier and a vacuum power booster. The power conditioner for generating all voltage needed for the operation of the RF devices and for housekeeping uses low-noise power supply topology incorporating high-efficiency, solid state power conversion circuits. A high-speed modulator is incorporated for pulse modulation of up to 10 KHz. This compact, conduction-cooled MPM is designed to operate in military airborne environments. Applications include electronic countermeasures (ECM), electronic warfare (EW) simulation, radars, multi-band communication systems, and EMI/EMC tests.
dB Control
xxx Compact Broadband Directional Coupler
Model 102020006 is a compact broadband directional coupler offering 6 dB of coupling over the frequency range of 2.0 to 20.0 GHz in a single, compact and lightweight package. It is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. These couplers offer solutions for many applications, including electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments.

Uncertain Times for DefenseWill OpenRFM Shake Up the Microwave Industry?
By Barry Manz

Throughout the history of the RF and microwave industry there has never been a form factor standardizing the electromechanical, software, control plane, and thermal interfaces used by integrated microwave assemblies (IMAs) employed in defense systems. Rather, every system has been built to meet the requirements of a specific system, which may be but probably isn’t compatible with any other system. It’s simply the way the industry has always responded to requests from subcontractors that in turn must meet the physical, electrical, and RF requirements of prime contractors. Read More...
