小型带状线交指滤波器的设计方法

一种小型带状线交指滤波器的设计方法

内容简介：介绍了一种小型带状线交指滤波器的研制过程,选用了薄型谐振杆并取消侧面调谐螺钉的方案实现小型低耗,提出了计算谐振杆端电容来确定杆长的设计方法,利用仿真软件进行了验证和分析,仿真和实测结果基本一致。

Abstract：The principle analysis of a small interdigital filter is presented. The stripline in- terdigital filter without side tuning screw has the advantages of small scale and low-loss. A new method of calculating the length of the rod is introduced. ANSOFT HFSS is used to simulate the filter. The performance of the filter is proved by simulation and practical tests.
