Duplexer
A duplexer is an electronic device that allows bi-directional (duplex) communication over a single path. In radar and radio communications 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 (often a waveguide filter), polarization (such as an orthomode transducer), or timing (as is typical in radar).〔 radar engineers have added the automatic switch (also called a duplexer) in the ... As soon as the transmitter stops sending a signal, the duplexer switches so that the receiver is now connected to the antenna.〕 ==Types==
