摘要

本文提出了一种具有相对紧密通道的紧凑型微带双工器。环形谐振器与正交馈电直接连接，形成带消除滤波器。在带消滤波器上加载分支，实现带通滤波器。本文设计的双工器由两个这样的带通滤波器组成。详细介绍了双工器的设计方法，并通过所制造的双工器的实验结果进行了验证。带通通道的中心频率分别为1.45Ghz和1.75Ghz。测量结果表明，双工器的两个通道相互靠近，具有低的插入损耗和高的带外抑制，与仿真结果吻合较好。

A Compact Microstrip Duplexer

In this paper, a compact microstrip duplexer with relatively close channels is proposed. The ring resonator and the orthogonal-feed are directly connected to form a band elimination filter. The band elimination filter is loaded with branches to realize the band-pass filter. The design of the duplexer in the article composed of two such band-pass filters. The design method of the duplexer is introduced in detail, and verified by the experimental results of the manufactured duplexer. The central frequency of the bandpass channels is 1.45Ghz and 1.75Ghz respectively. The measurement results show that the two channels of the duplexers are close to each other, with low insertion loss and high out-of-band rejection, which are in good agreement with the simulation results.
