微波带状线低通滤波器的设计制作与性能改善

讨论了带状线低通滤波器因实际制作的导带宽度发生变化引起滤波器性能下降时，如何改善滤波器性能的方法。我们采用惠普公司ＥＥＳＯＦ软件，对滤波器的结构和电气参数和分别作了灵敏度分析，以此为改善滤波器性能的依据。经实验对比，改进后的滤波器性能有了明显改善，且性能稳定。

Design, Development and Improvement of Microwave Stripline Low-pass Filter

This paper discusses a method how to improve the stripline low-pass filter when its performances are decreaced because the width of the conductive strips are changed after the process. The sensitivity of the structure and electrical parameter of the filter is analysed with the EESOF software of HP company, and it is taken as the basis to improve the performances of the filter.The experiments have proved that the performances of the improved filter is clearly increased and stable.
