摘要

提出了一种基于椭圆函数的小型化微带低通滤波器设计。该滤波器截止频率为2.5 GHz，通带纹波0.1dB，在2.85 GHz时阻带插入损耗大于20dB。它在阻带的2.945 GHz和4.015 GHz处提供两个有限衰减极点，衰减分别为35dB和50dB数量级。对所提出的滤波器进行了不同类型的设计表征，并提供了基于设计参数和尺寸的比较研究。

Design of a finite attenuation pole miniaturized S-band lowpass filter using elliptic function

A miniaturized microstrip lowpass filter design using elliptic function is presented in this paper. The proposed filter has a cut-off frequency of 2.5 GHz with passband ripple 0.1dB and stopband insertion loss greater than 20dB at 2.85 GHz. It provides two finite attenuation poles at 2.945 GHz and 4.015 GHz in the stopband having attenuation of the order of 35dB and 50dB respectively. Different types of design characterization have been investigated of the proposed filter and a comparative study based on design parameters and dimensions has been provided.
