摘要/Abstract

摘要： 射频连接器与微带线组件常用于通信系统电路中，而组件焊接过渡段的阻抗不连续会使电路中的信号损耗增大.针对该问题，本文对射频连接器与微带线组件焊接过渡段进行研究，基于传输线理论，建立焊接过渡段的等效电路模型.讨论了焊接过渡段特征阻抗不连续的原因，同时提出了补偿优化方案.此外，通过电磁场与电路的联合仿真，提取出补偿前后等效电路模型的电参数，从等效电路模型的角度分析了补偿方案对组件过渡段复杂电磁特性的影响.有限元仿真分析与实验测试结果显示，补偿后组件的性能显著提高，证明了补偿方案有效可行.

Abstract: The RF connectors and micro strip lines are commonly used in communication system circuits, and the characteristic impedance discontinuity caused by the welding transition section increases the signal loss in the circuit. In this paper,the welding transition section of the RF connector and micro strip line is studied. Based on the transmission line theory, the equivalent circuit model of the welding transition section is established. The reasons for the characteristic impedance discontinuity of the welding transition section are discussed, and the compensation schemes are proposed.In addition, the electrical parameters of the equivalent circuit model are extracted by the joint simulation of electromagnetic field and circuit. From the perspective of the equivalent circuit model, the influence of the compensation scheme on the complex electromagnetic characteristics of the solder transition section is analyzed. The finite element analysis and experimental results show that the matching and transmission performance of the compensated components is significantly improved, which proves that the compensation scheme is effective.

Key words: equivalent circuit model, welding transition section, impedance discontinuitiy, compensation
