A new family of high-reliability electromechanical relay switches, with designs that range from 2 to 10 million life cycles, is now stocked by Pasternack. Target applications include defence and commercial aviation, semiconductor manufacturing, communications, radar, SATCOM, test instrumentation, medical devices and many others. Pasternack's latest release of hi-rel RF switches consists of 42 new designs which include 38 connectorized models as well as four surface-mount devices that boast a small footprint and lower cost than traditional connectorized packages. A patented design of the actuator and transmission link has been optimized for magnetic efficiency and mechanical rigidity which 'guarantees' operation up to 10 million life cycles with excellent repeatability. The rugged MIL-STD-202 qualified construction of each RF relay switch is designed to withstand exposure to sine and random vibration and mechanical shock. New coaxial electromechanical switches from Pasternack are available in package styles using SMA & N Type connectors and include varieties from SPDT through SP12T. Frequencies range from DC to 40GHz depending on the model, operating voltage ranges from +12V to +30V, power ratings range from 5W to 700W and have high isolation up to 85dB and low insertion loss of 0.15dB at 1GHz. Additional features include indicators, a latching actuator, a failsafe actuator and TTL Inputs, says the company. "We are pleased to release one of the industry's largest off-the-shelf portfolios of electromechanical relay switches," said Tim Galla, active RF components product manager, Pasternack. "The patented rugged design features of these RF switches allow up to 10 million life cycles with excellent repeatability, compared to standard electromechanical relay switch designs."
