| Zusammenfassung: | Provided in the invention is a cavity-based filtering balun which comprises a cavity resonator. An input terminal PCB board and an output terminal PCB board are arranged at the two opposite sides of the cavity resonator; an input terminal slot line is arranged at one side, approaching the side of the cavity resonator, of the input terminal PCB board; and an input terminal microstrip line is arranged at the other side. A first slot hole that corresponds to the input terminal slot line completely is arranged at the position corresponding to the input terminal slot line on the side wall of the input terminal PCB board at the cavity resonator; an output terminal slot line is arranged at one side, approaching the side of the cavity resonator, of the output terminal PCB board and an output microstrip line is arranged at the other end; and a second slot hole corresponding to the output terminal slot line completely is arranged at the position corresponding to the output terminal slot line, onthe side wall of the out |
