This article presents the design of a microwave multisection combined Gysel–Wilkinson (MSCGW) power divider (PD) with arbitrary power division ratios, wide bandwidth (BW), and high power-handling capability (PHC). Exact design formulas for the $N$ -section PD are derived in the form of closed-form equations through even- and odd-mode analysis. In addition to the novelty of the structure itself, a straightforward design approach is presented based on the known analytical techniques to offer a guaranteed optimum design. The design approach is validated theoretically, analytically, and experimentally through measurements for simultaneously large BW and high PHC for several cases with different number of sections and power division ratios. Results confirm the BW of two-, three-, and four-section PDs as $\text {BW}_{N = 2} = 75$ %, $\text {BW}_{N = 3} = 90$ %, $\text {BW}_{N = 4} = 100$ %. Besides, compared with other similar works, the presented PD proves to be superior in terms of isolation, insertion loss, and compactness; making the proposed PD a very good candidate for microwave/mm-wave power divider/combiner applications.

具有任意功率分配比的多节组合Gysel-Wilkinson功率分配器

本文介绍了一种具有任意功率分配比，宽带宽（BW）和高功率处理能力（PHC）的微波多节组合Gysel-Wilkinson（MSCGW）功率分配器（PD）的设计。精确的设计公式 $ N $ 通过偶数模式和奇数模式分析，以闭合形式方程的形式导出截面PD。除了结构本身的新颖性之外，还基于已知的分析技术提出了一种简单的设计方法，以提供有保证的最佳设计。通过对部分截面数和功率分配比不同的几种情况下的大BW和高PHC同时进行测量，从理论上，分析上和实验上验证了该设计方法。结果证实了两节，三节和四节PD的BW为 $ \ text {BW} _ {N = 2} = 75 $ ％， $ \ text {BW} _ {N = 3} = 90 $ ％， $ \ text {BW} _ {N = 4} = 100 $ ％。此外，与其他类似作品相比，本文提出的局部放电在隔离度，插入损耗和紧凑性方面均被证明是优越的。使拟议的PD非常适合用于微波/毫米波功率分配器/组合器应用。
