摘　　要：根据微波电路设计的基本理论,详细地论述了微带发夹型滤波器的设计过程,及设计中各项参数的确定。并设计了一个抽头线发夹型带通滤波器,其中心频率为1.75GHz,带宽为100MH,完成了滤波器各参数值初值的确定,并结合ADS的优化仿真功能,得出了满足设计目标的版图仿真结果,论证了设计理论的正确性,证明了此方法适合于工程应用。According to the basic theory of microwave circuit design, the design process of microstrip hairpin-filter is presented in details. Then a tapped-line hairpin-filter with the center frequency of 1.75 GHz and the bandwidth of 100 MHz is made, and the determination of each parameter＇s initial value of the filter is completed, also the ADS is used for simulation and optimization. EM simulation result of meeting design objective proves that the design theory is correct and that the design method is adaptable to engineering applications.
