Electromechanical (EM) switches in the ASPDT series offer long-life operation (better than one million switching operations) from DC to 33.5 GHz with low loss and high isolation. The EM switches, which are available in single-pole, double-throw (SPDT) through single-pole, 10-throw (SP10T) configurations, are also available in normally open, failsafe, and latching actuator architectures. All models can be specified with or without indicators and transistor-transistor-logic (TTL) drivers. The switches, which feature low passive intermodulation (PIM), exhibit typical insertion loss of 0.5 dB at 18 GHz with 60 dB or better isolation. Maximum VSWR is 1.50:1 through 18 GHz. Switching time ranges from 15 to 30 ms. The switches are designed for operating temperatures from -25 to +65°C. A range of transfer switches also is available.
