In this letter, a wideband single-ended-to-balanced power divider (PD) with intrinsic common-mode (CM) suppression is presented. By introducing the hybrid microstrip/slotline structure, the CM signals can be naturally rejected. Under the differential-mode excitation, the feature of power division can be realized. The even/odd-mode equivalent circuits of the proposed PD are analyzed to guide the design. A practical PD is designed, simulated, and measured to verify the design method.

具有固有共模抑制功能的宽带单端平衡功率分配器

在这封信中，介绍了一种具有固有共模 (CM) 抑制功能的宽带单端平衡功率分配器 (PD)。通过引入混合微带/槽线结构，CM信号可以自然地被拒绝。在差模激励下，可以实现功率分配的特性。分析所提出的 PD 的偶/奇模式等效电路以指导设计。设计、模拟和测量实际 PD 以验证设计方法。
