Signal combiner circuit and signal combiner

The utility model discloses a signal combining circuit and a signal combiner, the signal combining circuit comprises a first-stage signal combining unit, the first-stage signal combining unit comprises N first-stage signal combining subunits, and the first-stage signal combining subunits are used for being in one-to-one communication connection with N channels of an information source, so that the N channels of the information source are combined; the signal combining circuit further comprises a second-level signal combining unit, the second-level signal combining unit comprises N second-level signal combining subunits and is used for combining N channel information sources output by the first-level signal combining unit again, and each second-level signal combining subunit comprises at least one output end and can support information source output of N channels. According to the utility model, N-stream MIMO is realized through the two stages of signal combining units, the method can be applied to an MIMO ind
