SP2T switch spans DC to 26.5GHz

Narda, an L-3 Communications company, has introduced the Model SEM124 single-pole, double-throw electromechanical switch that operates from DC to 26.5 GHz that is optimized for 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.

The Model SEM124 is a member of Narda's SEM Series of electromechanical microwave single-pole, double-throw switches that are available from stock. They include pulse latching and fail-safe models as well as models with TTL logic control and indicator circuits. In addition to the 26.5 GHz Model SEM124, there are models than cover DC to 12.4 GHz and DC to 18 GHz. The Model SEM124 switch is available from Narda for immediate delivery.
