RF Diplexers : 161 Products

The duplex is a special bidirectional three - terminal filter. The diplexer should not only couple the weak receiving signal in, but also feed the large transmitting power to the antenna, and the two are required to complete their functions independently without influencing each other. A pair of workers is the main part of the relay station of the different frequency duplex station. Its function is to isolate the transmitted and received signals, and the receiving and transmitting can work normally at the same time. It consists of two bands of bandpass filters with different frequencies to avoid transmitting signals from the local transmitter to the receiver.
