摘要

<FONT face=Verdana>由于受滤波器通带带宽、带内纹波、带外衰减量、插损、体积等性能参数的制约，设计和实现宽带中频抗混迭滤波器的技术要求往往比较高.首先介绍了中频带通采样技术及抗混迭滤波器设计的关键性能指标，电感、电容元件的主要参数与工作频率之间的变化关系及选用原则.然后，利用计算机仿真软件完成了滤波器的设计、元件参数配置与特性仿真，并提出了设计和实现高阶椭圆滤波器所采取的一系列措施，最后给出了9阶椭圆滤波器的设计电路及实测结果.

Abstract

<FONT face=Verdana>As it is restricted by the filter’s parameters

such as the passband bandwidth

inband ripple

outband attenuation

insertion loss and its volume and so on

designing and chieving broadband IF anti-aliasing filter is difficult.The IF bandpass sampling and antialiasing filter

and the relationship between the key parameters of the LC(inductors and capacitors) and the working frequency

and LC components selection principles are introduced.Then it achieved the designing of the filters

the actual components parameters configuration and characteristic <FONT face=Verdana>simulation with the computer simulation

and provided the methods to design and realize the higher-order elliptic filters.Lastly

gave the designed circuit and testing results of the 9-order elliptic filter.
