五臂混合环的分析改进和具有三种分配比的功率分配器的设计

本文用等效电路法对五臂混合环进行了分析,并得出两种改进方案。改进后的方案,既能使中心臂同环完全匹配,同第二对侧臂理想隔离,也能使第一对侧臂同环完全匹配,并彼此理想隔离。本文还提出用五臂混合环设计具有三种分配比的功率分配器的方法,给出了分析和计算公式。理论分析和实验结果基本一致。

ANALYSIS AND IMPROVEMENT OF THE FIVE-ARM RING AND DESIGN OF A FIVE-ARM RING POWER DIVIDER HAVING THREE DIFFERENT POWER RATIO S

Analysis by the use of equivalent circuit method is made for the five-arm ring, and two ways to improve it are found. The improved method can make the center arm entirely match the ring and isolated ideally from the second pair of side arms, and can make the first pair of side arms perfectly match the ring and both arms ideally isolated from each other. A method of design a five-arm ring power divider having three different power ratios is proposed. Analysis and calculation formulas are given. Theoretical resuls and experimental findings agree quite closely.
