微波带通滤波器的分析与设计

摘要
带通滤波器(BPF)是所有滤波器中使用最多、最重要,也是最难设计的一种滤波器。本文通过分析各种微波滤波器的特性,研究阶跃阻抗谐振器(SIR)的特性,研究采用SIR结构的微波带通滤波器的设计方法,以实现对这类滤波器的高效快速设计。同时,随着计算机性能的提高,以及微波CAD技术的进一步发展,高频电磁仿真软件仿真的精度和效率不断提高,可以将传统的等效电路设计方法与高频电磁仿真软件相结合,提高设计精度,缩短微波滤波器的研制周期,因此使用CAD软件技术来实现微波滤波器的设计及理论研究也具有现实意义。
本文就微波带通滤波器的设计方法、新的结构、滤波器阻带抑制的改善和滤波器的小型化进行了分析和研究。主要工作包括以下内容:
1、分析阶跃阻抗谐振器(SIR)的结构和相关原理,同时重点分析SIR的基本特性如:谐振条件、谐振长度、杂散频率和等效电路等。
2、研究利用SIR的原理设计微波带通滤波器的设计方法,并分析不同阻抗比的微波带通滤波器之间的特性。
3、研究SIR滤波器阻带抑制的改善方法,以消除寄生通带的影响。
4、研究利用EDA工具进行滤波器设计的方法。使用EDA工具模拟滤波器设计的实验,以此来设计滤波器,形成一种滤波器设计的通用和简单高效的方法,尤其是对于具有复杂几何结构的滤波器。
