RF duplexer is an electronic device that allows bi-directional (duplex) communication over a single path. In radar and radio communication systems, it isolates the receiver from the transmitter
while permitting them to share a common antenna. Most radio repeater systems include a duplexer. Duplexers can be based on frequency polarization, or timing.


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.
