提出了一种紧凑型宽带平衡-不平衡（BTU）异相功率分配器。该电路主要由三对级联耦合线和一个接地电阻组成。利用偶（奇）模法分析和传统的传输线理论，得到了一个差分输入端到两个不平衡输出端的等功率异相分配、高输出隔离度和良好共模抑制的闭合设计方程。此外，设计并制作了一个实验PD。良好的性能以及仿真结果与实测结果的一致性验证了我们的设计理论。
A compact wideband balanced-to-unbalanced (BTU) out-of-phase power divider (PD) is proposed in this letter. This novel circuit essentially consists of three pairs of cascaded coupled lines and a grounded resistor for output isolation. By using the even- (odd-) mode method analysis and the traditional transmission-line theory, closed-form design equations for equal power division with out of phase from one differential input to two unbalanced outputs, high output isolation and good common-mode suppression are obtained, simultaneously. In addition, an experimental PD is designed and fabricated. The good performance and the consistency between the simulated and measured results verify our design theory.
