| 摘 要： | 任意镜像阻抗平行耦合线滤波器与传统的平行耦合线滤波器相比,通过选择合理的镜像阻抗,可以得到合适的耦合线的宽度与缝隙,因而使滤波器更容易加工。首先从理论上推导了任意镜像阻抗平行耦合线滤波器的设计公式。根据此理论,设计了80Ω的任意镜像阻抗平行耦合线滤波器。通过EM仿真验证了设计公式的正确性与准确性。

| Abstract: | In contrast with conventional parallel coupled line filter,parallel coupled line filter with arbitrary image impedance has the advantage of obtaining the suitable width and gap of the coupled line by controlling the arbitrary image impedance.Based on the theory of filter,design equations are presented to make an arbitrary image impedance parallel-coupled line filter.Furthermore,to prove the validity and veracity of these equations,a filer of 80 Ω image impedance based on these equations is designed.The EM simulations show the validity and veracity of these equations. |
