Datasheet: DC To 26.5 GHz SP2T Electromechanical Switch - SEM124

Model SEM124 is a single-pole, double-throw electromechanical switch from Narda Microwave-East that operates from DC to 26.5 GHz with extremely low insertion loss, high isolation, and low VSWR.

The Model SEM124 switch features a fail-safe mechanism and an integrated indicator circuit. Actuating current is 160 mA at 28 VDC. The insertion loss of the switch ranges from 0.2 dB at 3 GHz to 0.7 dB at 26.5 GHz, and VSWR is 1.2:1 to 3 GHz and less than 1.7:1 at 26.5 GHz. Isolation is at least 50 dB at 26.5 GHz and 80 dB to 3 GHz.
