HMC349 and HMC849 RF Switch Modules

Switch a compatible RF signal between two paths with an HMC349 or HMC849 single-pole, double-throw module.

✅ Select between two signal routes - The SPDT arrangement provides a switching component for a compatible RF circuit.

✅ Connect through SMA interfaces - Coaxial connectors provide the described input and output connection points.

✅ Choose the frequency version - HMC349 and HMC849 options cover different stated operating-frequency limits.

Build the signal routing around the switch

An RF test or development setup may need to select one path rather than reconnect cables each time. A switch module provides that routing stage when its frequency, power and control requirements match the project.

Select the exact module and verify its control logic and signal limits before connecting. The 50-ohm interfaces must fit the surrounding RF chain; a switch board is not an amplifier or a complete test instrument.
