814MHz-849MHz/859MHz-894MHz Cavity Duplexer/Cavity Combiner

The CDU00814M00894M70NWP from Concept Microwave is a Cavity Duplexer with passbands from 814-849MHz at low band port and 859-894MHz at high band port. It has an insertion loss of less than 1.1dB and an isolation of more than 70 dB. The duplexer can handle up to 100 W of power. It is available in a module that measures 175x145x44mm. This RF cavity duplexer design is built with SMA connectors that are female gender. Other configuration, such as different passband and different connector are available under different model numbers.

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.
