What does an RF switch do?

A Radio Frequency (RF) switch is a device that routes high-frequency signals through transmission paths. They also support the integration of multiple radios that use a single antenna. The need for RF switch circuits is due to the increasing demand for wireless communications at higher frequencies and wider bandwidths.
