Model MS-SMA-020 is a single-pole, double-throw (SPDT) failsafe mechanical switch from Narda Microwave-East, an L-3 Communications company, capable of operating from DC to 3 GHz. It has less than 0.2 dB insertion loss but delivers 80 dB isolation and is designed to withstand more than 2 million switching operations. It is an excellent choice for automated test equipment, base station transmitters and receivers, and general-purpose applications. The switch, which can handle operating temperatures from -10 to +60 deg. C. It operates on 160 mA at +28 VDC and exhibits VSWR of 1.20:1. The compact switch measures 1.50 x 1.34 x 0.50 in. and is supplied with SMA female connectors.
