Fairview Microwave Announces New Waveguide Electromechanical Switches

08 December 2017

Fairview Microwave Inc. announced the development of waveguide electromechanical switches that cover frequency bands C, X, Ku, K and Ka, up to 40GHz.

The 28 switches in the series are configured as single-pole-double-draw and optional double-pole-double-throw (DPDT) configurations with latching self-cut-off actuators, TTL Logic and position indicators with manual override. The switches are designed for operating voltages of +12 V or +28 V and designed to sustain power capabilities of up to 12 kW in continuous-wave (CW) and 320 kW at peak.

Other features and specifications include:

  • A compact package design with integrated waveguide ports with grooved flanges and O-rings for pressurized operation (up to 30 PSIG).
  • Packages are fully weatherized for exposure up to 100 percent humidity.
  • Switches are available in a broad selection of waveguide sizes that include WR137, WR112, WR90, WR75, WR62, WR42 and WR28.
  • Operating temperature range runs from minus 40 degrees Celsius to 85 degrees Celsius.
  • Switches are rated for 250K lifecycles minimum.


The new series of switches are ideal for applications that include VSAT, SATCOM, radar, microwave radio, electronic warfare, electronic countermeasures, research and development, space systems and test instrumentation.

“Our new broadband waveguide electromechanical switches are ideal for designers who need to route either low or high power signals for applications that may involve microwave communications, broadcasting and radar. Instead of waiting several months for delivery, we have all 28 models available and ready to ship,” said Tim Galla, Product Manager at Fairview Microwave.
