摘　　要：基于集成无源器件(Integrated Passive Device,IPD)结构设计了一款7阶的椭圆低通滤波器,使用电子设计自动化软件(Advanced Design System,ADS)和三维全波电磁场仿真软件(High Frequency Structure Simulator,HFSS)对设计的滤波器进行仿真设计和优化。仿真结果分析显示,该低通滤波器截止频率为2.575 GHz,通带内的插入损耗低于1.5 dB,回波损耗低于-20 dB,在阻带对信号的衰减程度可以达到50 dB。在毫米波滤波器引入IPD结构,使得滤波器更加小型化,有利于优化滤波器的尺寸,得到较好的滤波器性能指标,是毫米波滤波器发展的一个重要方向。本设计的最终尺寸仅为650μm×720μm×85μm。Based on IPD(integrated passive device)structure,a seventh-order elliptic low-pass filter is designed.The electronic design automation software(Advanced Design System,ADS)and three-dimensional full wave electromagnetic field simulation software(High Frequency Structure Simulator,HFSS)are used to simulate and optimize the designed filter.Analysis and simulation results indicates that the cut-off frequency of the low-pass filter is 2.575 GHz,the insertion loss in the passband is less than 1.5 dB,the return loss is less than-20 dB,and the attenuation of the signal in the stopband can reach 50 dB.The introduction of the IPD structure in the millimeter wave filter makes the filter more miniaturized,which is conducive to optimizing the size of the filter and obtaining better filter performance indicators.It is an important direction for the development of millimeter wave filters.The final size of this design is only 650μm×720μm×85μm.
