Millimeter wave multi-channel spatial waveguide power distribution combiner and method

The invention discloses a millimeter-wave multi-channel space waveguide power distribution synthesizer and a method. The power distributor comprises a four-channel waveguide power distributors and four two-channel waveguide power distributors, a first port, four second ports and a first power allocation part are arranged in the four-channel waveguide power distributor, the first power allocation part is used for dividing one path of signal of electromagnetic wave into four paths of signals in equal proportion, a third port, two fourth ports and a second power allocation part are arranged in the each two-channel waveguide power distributor, the third port is connected with each second port, the second power allocation part is used for further dividing the four paths of signals into eight paths of signals in equal proportion, each path of signal is separately subjected to power amplification, the single path of signal subjected to amplification pass through the power synthesizer having the same structure with the power distributor, and multi-path power synthesis of electromagnetic signals are completed. The millimeter-wave multi-channel space waveguide power distribution synthesizer has the advantages of wide band, high capacity, high isolation, high efficiency, low loss and the like.
