Duplexers

Duplex is the main part of different frequency duplex station and repeater station. Its function is to isolate the transmitting and receiving signals, so that both receiving and transmitting can work normally at the same time.
It is composed of two bandpass filters of different frequencies to avoid transmitting signals from the local transmitter to the receiver.
