High Frequency (RF) RelaysA relay is an electrically operated switch that is used to control the flow of electrical current in a circuit. Relays can be used to switch electrical circuits on or off, or to control the direction of current flow, depending on the type of relay. High-frequency (RF) relays are a specialized type of relay that is designed to operate at high frequencies, typically in the range of 100 kHz to 1 GHz. RF relays are commonly used in applications such as wireless communication systems, RFID systems, and satellite communication systems, where the signals being transmitted and received have high frequencies. RF relays can be used to switch RF signals on or off, or to control the direction of RF signal flow, depending on the specific application.
