| 摘 要： | 从归一化低通滤波器出发,阐述了平行耦合线带通滤波器的工作原理和设计过程。给出了一个中心频率在C波段的带通滤波器设计实例。根据给定的滤波器技术指标,确定滤波器类型、结构和最佳级数。按照设计要求利用射频和微波设计软件ADS(先进设计系统)对带外抑制和插入损耗进行优化设计,从而达到要求的插损、带内波纹和理想的带外抑制特性。给出了优化的结果仿真图,结果表明优化结果与设计要求一致。

| Abstract: | Based on normalized low pass filter,the theory and design process of parallel coupled microstrip band pass filter are presented.An example of band-pass filter with center frequency in C band is given.According to the technical characteristics of filter,the type,structure and optimal stage number can be decided.The stop-band rejection and insertion loss can be designed by using design software ADS according to design requirement.Required insertion loss,in-band ripple and stop-band rejection characteristics can be achieved.Simulated results are given and they are consistent with design requirement. |
