The utility model discloses a TD-SCDMA three-frequency combiner, which belongs to the technical field of electronic information and mobile communication. The TD-SCDMA three-frequency combiner adopts a resonant cavity mode, and designs cavity filters respectively adaptable to TD (A), TD (B) and TD (C) network signals onto the same cavity body by applying fundamental principles of the filters. Besides, the TD-SCDMA three-frequency combiner adopts the mode of a common cavity, optimizes layout of the whole cavity body, decreases installing and debugging time, further uses aluminum materials for die sinking and die-casting of the cavity body, only needs plating 3-mu silver on the inner surface of the cavity body, and greatly saves cost. Moreover, the TD-SCDMA three-frequency combiner has high technical index restraint outside bands, small insertion loss and small volume, facilitates installing and debugging, improves the performance of the whole system, effectively simplifies TD system coverage, enhances the relia
