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。 In this paper, the five-arm hybrid ring is analyzed by the equivalent circuit method, and two improved schemes are obtained. An improved solution that perfectly matches the center arm with the ring and with the second pair of arms ideally allows the first pair of arms to be perfectly matched to the ring and perfectly isolated from each other. In this paper, a method of designing a power divider with three kinds of distribution ratio by using a five-arm hybrid ring is proposed. The analytical and computational formulas are given. Theoretical analysis and experimental results are basically the same.
