Microwave Coaxial Switch: Types, Specifications, and Applications
Release date：2026/7/22
Microwave coaxial switches are critical RF components designed for high-frequency applications operating from 1 GHz to 67 GHz. Combining the convenience of standard coaxial connectors with microwave-frequency performance, these switches are essential for radar, telecommunications, test equipment, and aerospace systems. This guide explores microwave coaxial switch technology, types, specifications, and applications.
Microwave coaxial switches bridge the gap between standard coaxial switches and waveguide switches, offering improved high-frequency performance compared to general coaxial switches while being more compact and easier to integrate than waveguide alternatives. They use precision connectors like SMA, 2.92mm, 2.4mm, and 1.85mm to achieve microwave-band operation.
