FMSW6375 is listed in the RF Switches range at ChipApex. The manufacturer field lists Fairview Microwave. Its product description is EM RELAY SWITCH 18 GHZ 24 V SMA. Review the specifications below when checking this part for your BOM.
The FMSW6375 is an electro-mechanical radio frequency switch manufactured by Fairview Microwave. It features a Single Pole Six Throw (SP6T) configuration with Normally Open contacts and SMA connectors. The device operates from DC to 18 GHz at 50 Ohms impedance. Key electrical specifications include an insertion loss of 0.15 dB, isolation of 80 dB, and power handling up to 49.54 dBm. It utilizes a 24V TTL control signal and supports up to 90W power.
Verify the specific datasheet version for precise thermal and mechanical tolerances before integration. Confirm that the 24V TTL control voltage aligns with the host system's logic levels. Ensure the operating environment remains within the specified temperature range to maintain reliable electromechanical actuation and consistent RF performance characteristics over time.
Select this component when a high-isolation SP6T switch is required for frequencies extending to 18 GHz. The 50 Ohm impedance matches standard RF systems. Consider the 24V coil voltage requirement for driver circuit design. This unit suits applications demanding low insertion loss and high power handling capabilities compared to solid-state alternatives.
Fairview Microwave produces specialized RF components for demanding environments. The FMSW6375 belongs to their electro-mechanical switch portfolio, designed for robust signal routing. These switches bridge the gap between low-loss performance and high-power handling, serving critical roles in professional RF engineering and defense applications where reliability is paramount.
No public confirmed substitute part numbers are available.
