Products Details


Cavity duplexers are three port devices used in Tranceivers (transmitter and receiver) to separate the Transmitter frequency band from the receiver frequency band. They share a common antenna while working simultaneously at different frequencies. A duplexer is basically a high and a low pass filter connected to an antenna.
