Description

technical field [0001] The invention relates to the technical field of communications, in particular to a duplexer. Background technique [0002] Duplexers are often used in existing mobile communication technologies. However, due to the relative isolation between transmission and reception of existing duplexers, the existing isolation effect is poor, and the size of the duplexer is improved to improve the isolation effect. , but the effect is not obvious. [0003] Therefore, in the prior art, there is a technical problem of poor transmission and reception isolation effects of the duplexer. Contents of the invention [0004] The invention provides a duplexer, which solves the technical problem of poor transmission and reception isolation effects of the duplexer in the prior art, and can further improve the isolation effect of the duplexer. [0005] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provid...
