RF and microwave attenuators for military EW and communications introduced by Fairview
April 19, 2016
ALLEN, Texas, 19 April 2016. Fairview Microwave Inc. in Allen, Texas, is introducing RF and microwave digitally controlled programmable attenuators for electronic warfare (EW), military and space communication systems, radar, and test and measurement applications.
The attenuators offer performance to 40 GHz and to 60 dB attenuation range with 0.03 dB minimum step size. These devices adjust the amplitude of signal levels in RF, microwave, and millimeter-wave systems.
The designs use PIN diode semiconductor technology that generates fast switching performance between attenuation states over wide frequency bands. This is used in transceiver RF and IF sections and in equipment applications such as signal generators to adjust the output level of test signals.
The programmable attenuators have integrated TTL driver logic control bit circuitry that ranges from 5 to 10 binary bits depending on the model. This number of bits benefits in precise and linear digital control of attenuation step sizes that can be as low as 0.03 dB to 1 dB maximum over the entire attenuation range.

The command and control interface is via a 15 pin female Micro-D socket or USB connector. The circuits are enclosed in environmentally sealed metal packages with epoxy paint finish with either stainless steel SMA or 2.92-millimeter connectors. Guaranteed operating performance covers a temperature range of -50 to 85 degrees Celsius.
