description The invention relates to a waveguide cable hybrid broadband system and a phase matching method. In view of multichannel waveguide cable broadband hybrid system, the method comprises the following steps: calculating the length of a waveguide centerline to obtain the length of each channel waveguide, calculating the average delay of different frequency signals in the channel waveguides to obtain a delay difference corresponding to the cables needing to be matched, then calculating an electrical length and a mechanical length of the cable according to the transmission properties of the coaxial cable, and adjusting the length of the cable to finally achieve the phase matching of the whole multichannel system. By adoption of the method, the problem that the existing phase matching method cannot be applicable to the broadband signal system and a non-equal waveguide cable hybrid system is solved, the method is not only applicable to the waveguide cable hybrid dot frequency system and is also applicable to the wavegu
