What Is an RF Microwave Switch and How Does It Work?

 

Release date：2026/7/22

 

An RF microwave switch is an electronic device that controls the routing of radio frequency (RF) and microwave signals. It acts as a single-pole multiple-throw (SPMT) or multi-pole multiple-throw (MPMT) switch, directing signals from one input to multiple outputs or vice versa.

These switches are designed to handle frequencies ranging from DC to over 100 GHz, making them suitable for applications in:

Cellular base stations and mobile networks
Satellite communications
Radar and electronic warfare systems
Test and measurement equipment
Medical imaging and treatment devices
Industrial process control
