Fairview Microwave Releases New Waveguide Electromechanical Relay Switches that Cover C, X, Ku, K and Ka Frequency Bands

Press release date: Dec 05, 2017

New Waveguide Electromechanical Relay Switches Range From 5.85 GHz to 40 GHz

Fairview Microwave Inc., a supplier of on-demand microwave and RF components, has introduced 28 new waveguide electromechanical relay switches from 5.85 GHz to 40 GHz that deliver full waveguide performance in C, X, Ku, K and Ka frequency bands. They are ideal for applications that include VSAT, SATCOM, radar, microwave radio, electronic warfare, electronic countermeasures, research and development, space systems and test instrumentation.

Fairview’s new waveguide electromechanical relay switches are configured for single-pole double-throw (SPDT) operation with latching actuators, self-cut-off, TTL logic, and position indicators with manual override. A shorting plate can be removed for optional double-pole double-throw (DPDT) operation. All switches incorporate a patented motor drive with arc suppression and include an environmentally sealed, quick-connect DC control connector and mate. These switches boast a compact package design with integrated waveguide ports with grooved flanges and O-rings for pressurized operation (up to 30 PSIG). They are available in a broad selection of waveguide sizes that include WR137, WR112, WR90, WR75, WR62, WR42 and WR28.

These waveguide electromechanical relay switches deliver desirable performance that includes high isolation levels up to 105 dB, and extremely low insertion loss down to 0.01 dB. Models are specified with operating voltages of either +12 or +28 Vdc and feature power handling capability of up to 12 kW CW and 320 kW peak (unpressurized, 10% duty cycle) in a break before make condition. These rugged designs operate in temperatures ranging from -40°C to +85°C, are rated for 250K lifecycles minimum, and packages are fully weatherized for exposure up to 100% humidity.

“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.

Fairview’s waveguide electromechanical relay switches are in stock and ready for immediate shipment with no minimum order quantity. For detailed information on these products, please visit https://www.fairviewmicrowave.com/rf-products/waveguide-electromechanical-switches-up-to-40-ghz.html.
