What is an RF Duplexer?

A duplexer is a 3-port device that allows the transmitter and receiver to use a single antenna while operating at the same/similar frequencies. It allows two-way communication over a single channel by isolating the receiver from transmitter while transmitting a signal and isolating the transmitter from the receiver while receiving a signal, allowing them to share the same antenna. In a duplexer there is no direct path between the transmitter and receiver. 


It can be thought of as a circulator i.e the signal from port 1 is routed to port 2 and the signal from port 2 is routed to port 3. Port 1 and Port 3 are isolated from each other. Duplexers are most often used in radars where both the transmitted and received signal have the same frequency.
