Hi-rel RF switches support 5-700W power ratings

Pasternack has rolled out a line-up of in-stock high-rel electromechanical relay switches with designs that range from 2-10 million life cycles. According to the company, the devices are aimed at applications such as 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 unique designs that include 38 connectorised models as well as four surface-mount devices that boast a small footprint and lower cost than traditional connectorised packages, the company indicated. A unique patented design of the actuator and transmission link has been optimised for magnetic efficiency and mechanical rigidity that 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.

The coaxial electromechanical switches from Pasternack are available in package styles using SMA & N type connectors and include varieties from single pull double throw (SPDT) through single pull 12 throw (SP12T). Frequencies for the RF switches 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 of these electromechanical relay switches include indicators, a latching actuator, a failsafe actuator and TTL inputs.

Pasternack's hi-rel electromechanical relay switches are available from stock.
