A directional coupler designed to split power equally between two ports is called a hybrid coupler. Hybrid coupler allows addition two or more signals, without interaction regardless of how close the frequencies of the signals may be. So it's mainly used to combination and division of the same frequency signal. An important advantage is that they have many outputs same as inputs. So, if a system needs multiple outputs, the hybrid matrix could be considered as a "lossless" combiner, and becomes a very important unit for DAS In-Building Networks.

Hicell supply a series of hybrid coupler with low PIM and low insertion loss solution for the multi standards or multi operators in DAS systems. Different numbers of input ports and output ports are avaliable.
