摘要

提出了一种具有耦合短路桩的紧凑型滤波器，该滤波器具有良好的带外消除性能。该结构可以在宽带或窄带滤波器的通带两侧产生传输零。给出了结构参数和仿真结果。样品滤波器的测试结果表明，在7.65 GHz至8.7 GHz的通带范围内，插入损耗小于0.4 dB，在8.81 GHz以上的通带范围内，消除值大于40 dB。

Economical Compact Filters with Coupled Shorting Stubs

A compact filter with coupled shorting stubs is proposed, which also has excellent out-of-band elimination. The structure can produce transmission zeros at both sides of the pass-band of a broadband or a narrow band filter. The configuration parameters and simulated results are presented. Tested results from a sample filter show that the insertion loss is lower than 0.4 dB in the pass-band from 7.65 GHz to 8.7 GHz and elimination higher than 40 dB from 8.81 GHz up.
