Abstract

This article presents design and implementations of cavity based band-pass filter with capacitive feed to implement external coupling. Normalized external coupling bandwidth is analyzed, calculated and plotted with equation. Only 3D EM simulation tool is used for simulations. Examinations are carried out for an X band frequency with fBW < 6.5% and VSWR >1.26:1. Measured results of proposed filter are found in good agreement with the simulation response.

基于腔体的双通道锐利抑制带通滤波器，采用电容馈电实现中等分数带宽

本文介绍了一种带电容馈电的腔型带通滤波器的设计与实现，以实现外部耦合。对归一化外耦合带宽进行了分析、计算和方程绘制。仅使用3D EM仿真工具进行仿真。对fBW < 6.5%， VSWR >1.26:1的X波段频率进行检测。该滤波器的实测结果与仿真结果吻合较好。
