摘要
通过对λ/4多阶阻抗变换器特性阻抗的研究,推导出在多阶阻抗变换器设计时馈线特性阻抗Z0、负载阻抗RL与匹配节传输线特性阻抗Zi之间应满足的关系,并通过设计实验验证了所描述的关系.该关系式可用于检验理想λ/4多阶阻抗变换器设计的正确性及设计方法的精度.
The formula for design of stepped impedance transformers was derived, obtaining a relationship among the characteristic impedance of transmission line; Z0, the loading impedance RL, and the characteristic impedance of the matching section; Z. And experiments were designed to validate the relationship. This relationship provides an effective way for assessing the design validity and precision of quarter-wave stepped impedance transformers.
