Duplexer is the main accessory of heterodyne duplex radios and repeaters. Its function is to isolate the transmitting and receiving signals to ensure that both receiving and transmitting can work properly at the same time. It is composed of two sets of bandstop filters of different frequencies to avoid the transmission of the local transmit signal to the receiver.
