24 October 2016

Electromechanical relay transfer switches from Fairview Microwave Inc. Electromechanical relay transfer switches from Fairview Microwave Inc.
Fairview Microwave Inc., a supplier of on-demand microwave and RF components, is offering a line of electromechanical relay transfer switches that cover frequencies from DC to 40 GHz, and feature low insertion loss and high isolation levels.

This product line comprises 43 unique electromechanical relay transfer switches that can be utilized for numerous applications to increase system- level capabilities and help simplify the overall design approach. With two input and two output ports, these coaxial transfer switches can connect two different instruments with two devices under test. Furthermore these RF switches can be used as “drop-out switches” for signal reversal or to bypass a component under test. These relay switches are popular in military communications, broadcast systems, SATCOM, test and measurement, and instrumentation applications.

Both +12 V and +28 V transfer switch designs offer a variety of features, including latching or failsafe actuators, indicators, self-cut-off, TTL logic, and suppression diodes. Broadband performance includes insertion loss as low as 0.2 dB min. and isolation greater than 80 dB. Some models feature power-handling capability up to 700 W (CW) at 1 GHz, and many units are RoHS- and Reach-compliant. Package outlines are compact and ruggedly built, supporting SMA, N-Type, TNC or 2.92 mm connectors.

The electromechanical relay transfer switches are in stock and ready for immediate shipment.
