基于ADS的滤波器类型选择对滤波性能的影响分析

内容简介：基于ADS设计滤波器一般设计方法，提出了滤波器设计过程中类型选择对器性能有一定的影响，利用ADS滤波器设计向导，进行3种不同类型滤波器的仿真，得到在滤波器的幅频特性和群延时上，给出仿真结果，并且对仿真结果进行对比分析，综合比较得出3种类型滤波器性能的优劣，为之后滤波器的设计给出一个指导方向，具有一定的理论意义。

Abstract：The general design method of ADS filter design based on the type of filter design, put forward in the process has a certain impact on the device performance, using ADS filter design wizard, simulation is performed for three different types of filter, the filter amplitude frequency characteristic and group delay, give out the simulation results, and comparing the results of the simulation analysis, comprehensive comparison of three types of filter’s performance, to design a filter direction, has certain theory significance.
