824MHz-849MHz / 869MHz-894MHz GSM Cavity Duplexer

The CDU00836M00881A01 from Concept Microwave is a Cavity Duplexer with passbands from 824-849MHz and 869-894MHz. It has an insertion loss of less than 1 dB and an isolation of more than 70 dB. The duplexer can handle up to 20 W of power. It is available in a module that measures 128x118x38mm. 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.
