These weatherized rugged devices have sealed quick-connect DC-control connectors, and operate in temperatures from -40 to 85 degrees Celsius.

LEWISVILLE, Texas – Fairview Microwave Inc. in Lewisville, Texas, is introducing a line of double-ridge waveguide electromechanical relay switches for electronic warfare (EW), very-small-aperture terminals (VSATs), radar, microwave radio, and test instrumentation.

These relay switches perform over broad radio frequency bands, and consist of 12 models that feature broadband multi-octave frequency coverage spanning 6.5 GHz to 40 GHz, latching self-cut-off actuators, TTL logic, and position indicators with manual override.

They come in SPDT and optional DPDT configurations and support WRD-650, WRD-750 and WRD-180 waveguide sizes. These designs deliver performance that includes 80 dB isolation, 2.5 dB insertion loss, and as much as 8.5 kilowatts of power handling.

These weatherized rugged, mil-grade packages for radar applications support an environmentally sealed quick-connect DC-control connector with mate, and are designed for 100 percent humidity exposure across operating temperatures from -40 to 85 degrees Celsius.
