    The high-frequency switch is designed to physically separate two ports TX (transmit) and RX (receive) of one common port Rx / Tx of mobile VHF transceiver. It is used in cases of creating a system of addition (division) of the antenna combiner on objects with a multitude of radio signals with a single antenna connector for the optimal number of antennas and for improving the electromagnetic compatibility. The operation of the RF switch is based on the property of the PIN - diodes to pass or block the RF signal in the presence or absence of a control DC voltage. When RF power is applied, the switch automatically switches the common Rx / Tx port to the Tx OUT port. In the absence of RF power, the Rx IN port is connected to the common Rx / Tx port.
