平行耦合微带线带通滤波器分析与设计
Analysis and Design of Parallel Coupled Microstrip Line Bandpass Filter
摘要
Abstract
In view of large size,table checking required and difficult optimization in the design of parallel coupled microstrip line bandpass filter,a design method of parallel coupled microstrip line bandpass filter based on ADS is proposed.Based on thorough theoret⁃ical analysis,it is found that the parallel coupled microstrip line bandpass filter system impedance microstrip line is not resonant,so the length can be as short as possible to reduce the circuit size.A prototype of a lowpass filter is obtained by using ADS software,eliminating the trouble of the look⁃up table;In the layout optimization,the tuning method is more effective than the optimization method.The simula⁃tion results show that the system impedance microstrip line is 2.5 mm long,the center frequency is 5 GHz,and the relative bandwidth is 10%.This method can reduce the size of filter and not reduce the performance of the filter.The design and implementation of this method is fast and efficient.关键词
