RF Coaxial Switch (also called microwave switch) is a device that routes high-frequency signals through transmission paths. RF microwave switches are widely used in microwave test systems for signal routing between the instrument and equipment. Integrating switches into a switch matrix system enables you to route signals from multiple instruments to a single or multiple DUTs. Multi-port connection via RF switch, allowing multiple paths testing to be performed using the same system settings without frequent disconnections.
Lair Microwave independently develops and produces RF coaxial switches with a frequency of DC-40GHz and interface types such as SMA, N, 2.92mm, 2.4mm, BNC, TNC, 7/16, etc., which are widely used in ATE automatic testing, mobile phone testing production lines, WLAN / WIFI / LTE and other mobile communication equipment testing.
