This article presents a large power division ratio (PDR) branch-line coupler. The proposed coupler can realize the differential signal pass-through from the balanced-to-balanced ports and the single-ended signal coupling from the balanced to unbalanced ports. The authors demonstrate the proposed coupler using a microstrip circuit prototype with a PDR of 10 dB.

具有差分直通和差分到单端耦合的大功率分配比支线耦合器


本文介绍了一种大功率分配比 (PDR) 支线耦合器。所提出的耦合器可以实现从平衡端口到平衡端口的差分信号直通以及从平衡端口到不平衡端口的单端信号耦合。作者使用 PDR 为 10 dB 的微带电路原型演示了所提出的耦合器。
