| 摘 要： | 通过在带状线交指滤波器的输入端并联一个λ／4开路谐振器,构成了一种改进型的交指带通滤波器。该滤波器在阻带特定频率处产生传输零点,且该零点位置可任意选择,较大地改善了滤波器带外的抑制。结合ADS仿真软件设计了一个C波段带传输零点的带状线交指滤波器,仿真结果表明,该方法可行有效,适合于工程应用。

| Abstract: | An improved interlaced bandpass filter is set up by parallel connecting a λ/4 open resonator at the input port of the stripline interlaced filter. This filter can produce transmission zero at the special frequency of band stop and the zero position can be adopted anywhere, which greatly improves the out-band rejection of filter. This paper designs a C-band stripline Interlaced filter with transmission zero combining with ADS simulation software. The simulation result shows this method is feasible andeffective,is suitable for engineering. |
