在本文中，我们提出了一种新的分析设计技术来实现一个小型化的3路功分器（3 PD），支持宽带操作的频带比从1-6.5。建议的3 PD配置包括四个不同的相称的传输线和两个不同的隔离电阻器。本文利用公度传输线的双频特性和重组方法，进行了全面的理论分析，得到了一套全新的严格的设计方程。此外，相应的文本S参数方程推导，这表明所提出的3 PD的宽带能力，通过几个设计实例进行验证。所提出的技术的一个制造的原型表现出良好的输入回波损耗（>15 dB），输出回波损耗（>15 dB），以及插入损耗（16 dB）从0.94-2.24 GHz，甚至实现了132%的分数带宽（频带比=4.96），考虑到10 dB的参考。这种简单而紧凑的平面结构所提供的不同特性和性能使该设计成为微波IC、天线馈电网络和Doherty功率放大器等应用的理想选择。
In this paper, we present a novel analytical design technique to implement a miniaturized 3-way power divider (3PD) supporting a wideband operation with a band ratio from 1-6.5. The proposed 3PD configuration comprises four distinct commensurate transmission lines and two different isolation resistors. A comprehensive theoretical analysis is conducted to arrive at a set of completely new and rigorous design equations by utilizing the text dual-band behavior of the commensurate transmission line and the recombinant approach. Additionally, corresponding text S-parameter equations are derived, which manifest the wideband capability of the proposed 3PD, as validated through several design examples. A fabricated prototype of the proposed technique exhibits excellent input return loss (>15 dB), output return loss (>15 dB) as well as insertion loss (16 dB) from 0.94-2.24 GHz and even achieves a fractional bandwidth of 132% (band ratio=4.96) considering a 10 dB reference. The different features and performance provided by this simple yet compact planar structure make the design an ideal choice for applications such as microwave ICs, antenna feed networks, and Doherty power amplifiers.
