摘要

摘要本文提出并验证了设计宽带微带正交 3 分贝功分器的分析方法。本文提出的正交功分器利用双级耦合线威尔金森功分器和改进型移相器在一个输出端口产生相位延迟。与传统的 T 型存根相比，所提出的 T 型存根 Tweaked 配置在不增加任何制造复杂性的情况下表现出更好的性能，从而提高了正交功分器的性能。在测试中，所提出的正交威尔金森功分器的工作频率为 2-4.5GHz（分数带宽 FBW = 76.9%），阻抗为 10dB，隔离带宽为 15dB。此外，该设计具有非常好的相位和振幅平衡，相位不平衡为 7°，振幅不平衡为 1 dB。

Design and Analysis of a Novel Broadband Tweaked T-shaped Stub-loaded Quadrature Power-Splitter

Abstract

In this paper analytical approach to design a broadband microstrip quadrature 3-dB power splitter is proposed and validated. The proposed quadrature splitter in this paper utilizes a double-stage coupled line Wilkinson power divider in conjunction with a modified phase shifter to induce phase delay at one output port. Compared with the conventional T- shaped stub, the proposed configuration of Tweaked T-shaped stubs exhibits better performance without adding any fabrication complexity, which in turn improves the performance of the quadrature power splitter. In testing, the proposed quadrature Wilkinson power divider covers 2–4.5 GHz (fractional bandwidth FBW = 76.9%) working frequency with 10-dB impedance and 15-dB isolation bandwidth. Furthermore, this design has a very good phase and amplitude balance, with a 7° phase and 1 dB amplitude imbalance.
