摘要

本文提出了一种由阶跃阻抗变压器组成的紧凑型宽带滤波器。阶跃阻抗变压器由两个短路插脚和一对开路插脚负载。设计并仿真了一个工作频率为3.71 GHz ~ 7.28 GHz的宽带带通滤波器。所设计的滤波器也被制作出来进行验证。该滤波器的带宽为60%，面积为8.6 × 8.35 mm2。因此得到了一个紧凑的宽带滤波器。

A compact wideband filter utilizing stepped-impedance transformer and stubs

This paper proposes a compact wideband filters consisting of a stepped-impedance transformer. The stepped-impedance transformer is loaded by two short-circuited stubs and a pair of open-circuited stubs. A wideband bandpass filter operated from 3.71 GHz to 7.28 GHz has been designed and simulated. The designed filter has also been fabricated for validation. The fabricated filter exhibits a 60% bandwidth and occupies an area of 8.6 × 8.35 mm2. A compact and wideband filter is therefore obtained.
