FMSW7279

RF Switches Overview

The FMSW7279 is an electromechanical RF relay switch manufactured by Fairview Microwave. It operates as a single-pole double-throw (SPDT) failsafe switch with a frequency range extending from DC to 43 GHz. The device is designed for high-frequency applications, supporting a maximum power handling capacity of 10 watts and maintaining low insertion loss between 0.2 and 1.2 dB. It functions on a 12VDC supply voltage with a current draw of 200 mA. The component utilizes solder termination for circuit integration.
