Waveguide electromechanical relay switches range from 5.85 to 40 GHz

May 11, 2017 // By Julien Happich
Pasternack has introduced 28 new waveguide electromechanical relay switches that offer full waveguide performance covering C, X, Ku, K and Ka frequency bands from 5.85 GHz to 40 GHz.

The units are configured for single-pole double-throw (SPDT) operation with latching self-cut-off actuators, 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.

The compact package design features integrated waveguide ports with grooved flanges and O-rings included for pressurized operation (up to 30 PSIG). These waveguide electromechanical relay switches deliver performance down to 0.01 dB typical insertion loss and up to 105 dB typical isolation. Models exhibit switching speed levels that range from 54 to 76ms typical, and are available with either +12 or +28 Vdc nominal voltages. Power handling capability is up to 12kW CW and 320 kW peak (unpressurized, 10% duty cycle).  These rugged designs operate across a temperature range of -40°C to +85°C, are fully weatherized for up to 100% humidity exposure and have an operating life of 250K cycles minimum.
