RF Duplexer-parameter
RF Duplexer is pilot frequency duplex radio station,  the main parts relay station , it's function is to isolate the transmit and receive signal , guarantee the the receive and transmit can work at the same time.It is made of two groups of different frequency band stop filter, avoid the native emission signal transmission to the receiver.
