The Model SEM124, a single-pole, double-throw electromechanical switch, operates over a frequency range from dc to 26.5 GHz with low insertion loss, high isolation, and a low VSWR. It features a fail-safe mechanism and an integrated indicator circuit. Actuating current is 160 mA at 28 Vdc and insertion loss ranges from 0.2 dB at 3 GHz to 0.7 dB at 26.5 GHz. Other specs include a VSWR of 1.2:1 to 3 GHz and less than 1.7:1 at 26.5 GHz and an isolation figure of at least 50 dB at 26.5 GHz and 80 dB to 3 GHz. The component is one of several SEM series switches that 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, the series includes models that cover dc to 12.4 GHz and dc to 18 GHz. NARDA MICROWAVE - EAST, Hauppauge, NY. (631) 231-1700.
