A new simple computational tool is proposed for the synthesis of multi-section coupled-line filters based on combined modified planar circuit method (MPCM) and transmission line method (TLM) analysis, referred to as MPCM-TLM. Due to its fundamentally simple architecture, the presented tool offers significantly faster optimization of coupled-line filters – for exactly the same initial simulation set-up – than other costly commercially-available tools, giving equally reliable results.Validity and accuracy of the proposed tool have been verified through the design of 3rd, 5th, and 7th order coupled-line filters and comparative analysis between results obtained from the proposed approach and the high-frequency structure simulator. A remarkable 99% time reduction in the analysis is recorded in the case of 7th order filter using the proposed tool, for almost identical results to HFSS. Therefore, it can be confidently claimed that the proposed technique can be used as a reliable alternative to existing complex, costly, processor-intensive CAD tools.

Couplinator：基于 MPCM-TLM 技术的多段耦合线滤波器合成的简单计算工具

提出了一种新的基于改进平面电路法（MPCM）和传输线法（TLM）分析的多段耦合线滤波器合成的简单计算工具，称为MPCM-TLM。由于其基本简单的架构，与其他昂贵的商用工具相比，所提出的工具提供了明显更快的耦合线滤波器优化 - 对于完全相同的初始模拟设置 - 提供同样可靠的结果。所提出工具的有效性和准确性通过 3 阶、5 阶和 7 阶耦合线滤波器的设计以及从所提出的方法和高频结构模拟器获得的结果之间的比较分析来验证。在使用建议工具的 7 阶滤波器的情况下，分析时间显着减少了 99%，结果与 HFSS 几乎相同。因此，可以自信地声称，所提出的技术可以用作现有复杂、昂贵、处理器密集型 CAD 工具的可靠替代方案。
