Abstract

In this paper, a novel analytical design technique is presented to implement a coupled-line wideband Wilkinson power divider (WPD). The configuration of the WPD is comprised of three distinct coupled-line and three isolation resistors. A comprehensive theoretical analysis is conducted to arrive at a set of completely new and rigorous design equations utilizing the dual-band behavior of commensurate transmission lines. Further, the corresponding S-parameters equations are also derived, which determine the wideband capability of the proposed WPD. To validate the proposed design concept, a prototype working at the resonance frequencies of 0.9 GHz and 1.8 GHz is designed and fabricated using 60 mils thick Rogers' RO4003C substrate. The measured result of the fabricated prototype exhibits an excellent input return loss > 16.4 dB, output return loss > 15 dB, insertion loss < 3.30 dB and a remarkable isolation > 22 dB within the band and with a 15 dB and 10 dB references provide a fractional bandwidth of 110% and 141%, respectively.

摘要

本文提出了一种新颖的分析设计技术，用于实现耦合线宽带威尔金森功率分配器（WPD）。该WPD的结构由三条不同的耦合线和三个隔离电阻组成。利用匹配传输线的双频特性，进行了全面的理论分析，得出了一组全新且严格的设计方程。此外，还推导了相应的S参数方程，这些方程决定了所提出的WPD的宽带性能。为验证所提出的设计概念，使用60密耳厚的罗杰斯RO4003C基板设计并制作了一个工作在0.9 GHz和1.8 GHz谐振频率的原型。所制作原型的测量结果显示，在频段内具有出色的输入回波损耗> 16.4 dB、输出回波损耗> 15 dB、插入损耗< 3.30 dB以及显著的隔离度> 22 dB，以15 dB和10 dB为参考，分别提供了110%和141%的分数带宽。
