Abstract
A circulator section in a transceiver receives a transmit signal and an antenna signal and provides them respectively to an antenna and to an electronic switch. The electronic switch operates synchronously with the duplex mode of the transceiver to connect the antenna to a receiver when the transceiver is in receive mode, and to a matched load when it is in transmit mode. Since the signal path of any portion of the transmit signal reflected by a mismatched antenna is terminated by the load, power which otherwise might be reflected back to the transmitter and thereby damage it is instead absorbed by the matching load.
