摘要

在分析带通滤波器等效电路类型与特点的基础上,提出了一种简单的且具有两个传输零点的新型带通滤波器结构,有效解决了低介电常数多芯片组件(MCM)集成带通滤波器的性能与面积的问题.通过实际设计加工测试了一款中心频率为1.61GHz、带宽为260MHz的带通滤波器,插入损耗为0.71dB,驻波1.2,测试结果与仿真结果一致,器件整体尺寸为3.2mm×2.4mm×0.6mm.

Abstract

A simple and novel band-pass filter have two transmission zeros was structured based on the analysis of the prototype bandpass filter equivalent circuit of the type and characteristics and use of T-equivalent circuit model and the combination of the two capacitive coupling between Input and output ports.An effective solution to a Low K of multi-chip module (MCM) integrated bandpass filter performance and space.A bandwidth of 260MHz,the center frequency of 1.61 GHz band-pass filter was designed and measured by used of Low Temperature Co-fired Ceramic (LTCC) technology.The simulated results are compared with the measured data,and good agreement is reported,the overall area of 3.2mm×2.4mm×0.6mm,insertion loss 0.71dB,VSWR1.2.
