[0002] In recent years, with the emergence of a large number of large shopping malls, hotels, subways, etc., the indoor distribution system has shown new characteristics. In order to improve the construction speed of the communication network and reduce the cost of repeated construction, the mode of sharing the signal distribution system by multiple communication systems has been widely used. Sometimes, it is necessary to couple out part of the signals from two co-frequency signals for combining, and the remaining signals are transmitted normally. In this case, a system usually needs to be composed of two couplers and a co-frequency combiner, which occupies a large space and has many interfaces. The co-frequency combiners on the market have no coupling interfaces, and a single coupler cannot achieve the dual-channel co-frequency combining function.
