In a conventional power divider, power dividing network and isolation network are usually independent of each other. To reduce the size of out-of-phase power divider with arbitrary power ratio, coupled microstrip lines are proposed to facilitate power dividing and isolation of a power divider simultaneously in this article. Formulations have been derived for the proposed out-of-phase power divider with arbitrary ratio. Two compact power dividers are implemented on the printed circuit board (PCB) with power ratio $k^{2} = 9$ and $k^{2} = 1000$ . It can be observed that there is a satisfactory agreement between the simulated and measured results.

一种紧凑型任意比异相功率分配器的新设计

在传统的功率分配器中，功率分配网络和隔离网络通常是相互独立的。为了减小具有任意功率比的异相功率分配器的尺寸，本文提出耦合微带线以同时促进功率分配器的功率分配和隔离。已为提出的具有任意比率的异相功率分配器推导出公式。在印刷电路板 (PCB) 上实现了两个具有功率比的紧凑型功率分配器 $k^{2} = 9$ 和 $k^{2} = 1000$ . 可以观察到，模拟结果和测量结果之间存在令人满意的一致性。
