Fairview Microwave has introduced a new series of double ridge waveguide electromechanical relay switches that perform over broader frequency bands. They are well suited for applications involving electronic warfare, electronic countermeasures, VSAT, radar, microwave radio, research and development, and test instrumentation.

Fairview’s new comprehensive line of double ridge waveguide electromechanical switches includes 12 models that feature broadband multi-octave frequency coverage spanning 6.5 to 40GHz, latching self-cut-off actuators, TTL logic, and position indicators with manual override.  They are offered in SPDT and optional DPDT configurations and support WRD-650, WRD-750 and WRD-180 waveguide sizes. These designs deliver highly desirable performance that includes 80 dB isolation, 2.5 dB insertion loss and up to 8.5kW power handling capability.

“Typically, suppliers require a 16 -20+ week lead time and minimum order quantities (MOQs) for these types of products. With this in stock product line, we’re able to provide RF designers a comprehensive selection of broader-band, double ridge waveguide electromechanical switch designs for urgent proof-of-concept or prototype applications, with no MOQ,” said Tim Galla, Product Line Manager.

These fully-weatherized, rugged, mil-grade packages support an environmentally-sealed quick-connect DC-control connector with mate. They are designed for 100% humidity exposure across a -40 to +85°C operating temperatures. 

Fairview Microwave’s new double ridge waveguide electromechanical relay switches are in stock and available for immediate shipping with no minimum order quantity required.
