摘要
设计了一款基于集成无源器件(IPD)技术的无反射带阻滤波器。它能将阻带反射回的信号吸收掉,从而可以提高电路的线性度。在无反射低通滤波器的电路拓扑结构下,采用变换的形式设计出电路,使用电子设计自动化软件(ADS)和三维全波电磁场仿真软件(HFSS)完成无反射带阻滤波器的建模与仿真。该滤波器的中心频率为4.11 GHz,阻带频段为1.52~6.70 GHz,阻带抑制大于等于14.47 dB,通带插入损耗小于0.7 dB,相对带宽为79%。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,模型的整体尺寸仅为0.9 mm×1 mm×0.1 mm。通过三维电磁仿真实验,验证了该无反射带阻滤波器的可行性。
A reflectionless band-stop filter was designed based on integrated passive device(IPD)technology.It can absorb the reflected signal,which can improve the linearity of the circuit.According to the circuit topology structure of the filter,the circuit was designed by transformation method.Modeling and simulation were performed for the filter using electronic design automation(ADS)software and three-dimensional full-wave electromagnetic field(HFSS)software.The central frequency of the filter is at 4.11 GHz with stopband from 1.52 GHz to 6.70 GHz.The stopband rejection,passband insertion loss and relative bandwidth is≥14.47 dB,<0.7 dB,and 79%respectively.By using the IPD structure for the millimeter wave filter,the filter is optimized and miniaturized with overall size of 0.9 mm×1 mm×0.1 mm.The reflectionless band-stop filter was verified by three-dimensional electromagnetic simulation experiment.
