791MHz-821MHz/925MHz-960MHz/1805MHz-1880MHz/2110MHz-2170MHz/2620MHz-2690MHz Cavity Combiner

The CDU00791M02690A01 from Concept Microwave is a 5-bands Cavity Combiner with passbands from 791-821MHz&925-960MHz&1805-1880MHz&2110-2170MHz&2620-2690MHz. It has an insertion loss of less than 1.5dB and an isolation of more than 75 dB. The combiner can handle up to 20 W of power. It is available in a module that measures 129x116x74mm. This RF cavity combiner 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 combiner are six 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 combiner is basically a high and a low pass filter connected to an antenna.
