RF Duplexer
A cavity duplexer is a special type of duplexer used in wireless communication systems to separate transmitted and received signals in the frequency domain. The cavity duplexer consists of a pair of resonant cavities, each specifically responsible for communication in one direction.
The working principle of a cavity duplexer is based on frequency selectivity, which uses a specific resonant cavity to selectively transmit signals within the frequency range. Specifically, when a signal is sent into a cavity duplexer, it is transmitted to a specific resonant cavity and amplified and transmitted at the resonant frequency of that cavity. At the same time, the received signal remains in another resonant cavity and will not be transmitted or interfered with.
