Kathrein 793533 RF Combiner Radio Frequency Module

The Kathrein 793533 is a dual band combiner used within mobile network base station antenna feeder systems, allowing two separate frequency bands to be combined onto a single shared antenna line. Dual band combiners of this type are used where a site needs to run two cellular technologies or frequency bands, for example GSM and UMTS, or 2G and 3G/4G overlays, through the same antenna infrastructure, reducing the number of feeder cables, antennas and tower positions required and simplifying site logistics where space or planning permission is limited. The combiner sits in the RF chain between the base station radios for each band and the shared antenna, engineered to maintain low insertion loss and high isolation between the combined bands. Kathrein is a long-established German manufacturer of antenna and RF site infrastructure, and its combiner range is widely used by mobile operators consolidating multi-band radio equipment onto shared antenna systems.
