无线通信系统中微带带通滤波器的谐波抑制方法
内容简介：现代通信系统对滤波器的要求越来越严格，要求滤波器体积小、重量轻、制造成本低、性能好且稳定，而滤波器的谐波严重影响其性能。文章从滤波器多年的发展状况总结了几种谐波抑制方法，提出了一种利用三截面阶梯阻抗和过耦合技术结合的方法，使得阻带达到了5倍中心频率。
Abstract：Modern communication systems are increasingly stringent demands on the filter, the filter requirements, small size, light weight, low cost, good performance, stable, and the harmonic seriously affect the filter performance. This article from the development of filter in years, summarizes several method of harmonic suppression, presents a method of using a three-section ladder impedance and over-coupling, making the stop-band up to 5 times of the center frequency.
