FMSW6440

RF Switches Overview

The FMSW6440 is a SPDT electromechanical coaxial switch manufactured by Fairview Microwave. It operates from DC to 26.5 GHz with a 50 Ohm impedance. The device features a latching mechanism with self cut-off and suppression diodes, requiring a 28 V coil voltage. Key electrical parameters include a maximum insertion loss of 0.3 dB, a VSWR of 1.3, and isolation of 50 dB. It supports up to 90W power handling and offers a mechanical life of 5 million cycles. The unit utilizes solder terminals for connection.

RF Switches Procurement Notes

Verify the specific datasheet version prior to ordering, as specifications may be subject to change. Confirm that the 28V control voltage aligns with your system's available drive capabilities. Ensure the solder terminal interface matches your PCB layout requirements. Check for any regional shipping restrictions or supply limitations before finalizing procurement plans.

RF Switches Selection Notes

Select this component when high-frequency performance up to 26.5 GHz is required alongside significant power handling. The latching feature reduces continuous power consumption compared to non-latching alternatives. Consider the 50 dB isolation level for applications demanding strict signal separation. Verify that the physical dimensions and solder termination style fit within the designated enclosure space.
