摘要

本文推导出一种扩展的传输线理论，并利用该理论为千赫兹和兆赫兹范围内的铁氧体传输线变压器生成简单的宽带模型。利用对传输线的扩展描述，可以轻松地将紧凑的元件插入设备电路中。通过对各种变压器的测量验证了由此产生的模型，并得出了准确的定性和定量预测。最后，使用 CST Studio Suite 进行的仿真分析证实了扩展传输线模型的内部物理行为，特别是其对对称电流和非对称电流的区分。

Extended Transmission Line Theory and Its Application to the Broadband Modeling of Ferrite-Based RF Transformers

In this article, an extended transmission line theory is derived and utilized to generate simple broadband models for ferrite transmission line transformers in the kilo- and megahertz range. Using the extended description of a transmission line leads to a compact element that can easily be inserted into the circuit of a device. The resulting models are verified through measurements of various transformers and produce qualitatively and quantitatively accurate predictions. Lastly, simulation analysis using CST Studio Suite confirms the internal physical behavior of the extended transmission line model, specifically its distinction between symmetrical and unsymmetrical currents.
