description The utility model relates to a high-performance duplexer based on an LTCC technology, and belongs to the technical field of duplexers. The LTCC duplexer comprises an LTCC substrate layer, a duplexer circuit structure is formed on the LTCC substrate layer, the duplexer circuit structure is composed of a low-pass filter circuit and a band-pass filter circuit, the low-pass filter circuit comprises a first inductor and a first parallel resonator which are connected in series between a common input port and a low-frequency output port, and the band-pass filter circuit comprises a second inductor and a second parallel resonator which are connected in series between the common input port and the low-frequency output port. A grounded first capacitor is connected between the first inductor and the first parallel resonator, the band-pass filter circuit comprises a first series resonator and a second series resonator which are connected in series between the common input port and the high-frequency output port, and a th
