摘要

给出了微带短管引脚衰减器特性的分析结果。结果表明，pin衰减器的相位和幅度特性是由pin二极管电阻变化时谐振系统品质因数的变化决定的。在频率响应不均匀度在0.3 dB以内的5%频带内，相位漂移约为30-40/声压度/。分析了几何尺寸对输入SWR的影响。

Phase characteristics of stub PIN-attenuators

Analysis results of microstrip stub PIN-attenuator characteristics are presented. It is shown that phase-and-amplitude characteristics of PIN-attenuators are determined by a variation of the resonant system figure-of-merit while PIN-diode resistance changes. In 5% band at frequency response nonuniformity within 0.3 dB, the phase drift is about 30-40/spl deg/. The influence of geometrical dimensions on input SWR has been analyzed.
