A Frequency Combiner is designed based on single branching directional coupler theory. It is able to realize the power combination of two-way / co-frequency signals thereby sharing one common port. Compared with a typical signal splitter, a frequency combiner has very low insertion loss, VSWR values and high port isolation.  

Suitable for LTE/ GSM / CDMA / DCS / PCS & WCDMA distributed antenna systems or other outdoor coverage solutions. It's able to combine signals of different communication standards and output them to the same antenna feed.
