基于SIR的同轴腔体带通滤波器设计
Coaxial cavity bandpass filter design based on SIR
摘要
Abstract
According to the basic principle of stepped impedance resonators SIR, a miniaturization coaxial cavity bandpass filter was designed by using λg/4 type SIR as the basic harmonic unit.Simulation results show that the length was compressed 56.7％ compared to the actual size λg/4, the passband return loss was less than 17.5 dB, insertion loss was less than 0.1 dB, band rejection reaches -38.8 dB.This filter fully meets the modern mobile communication systems requirements of miniaturization, low insertion loss, high selectivity, so it can be widely used in modern mobile communication systems.关键词
