Switches offer high performance covering DC to 40 GHz

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 & measurement, and instrumentation applications.

Both +12V and +28V transfer switch designs offer a variety of features which include latching or failsafe actuators, indicators, self-cut-off, TTL logic, and suppression diodes. Superior 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 Watts (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 2.92mm connectors.

“Fairview’s expanded family of 43 different high-rel electromechanical relay transfer switches are rated up to 5 million lifecycles and can be utilised for numerous applications to increase system level capabilities and can help simplify the overall design approach,” explains Brian McCutcheon, General Manager at Fairview Microwave. “We are committed to offering solutions and technical support to designers that require urgently needed RF components.”

Fairview’s new electromechanical relay transfer switches are in-stock and ready for immediate shipment.
