| 摘 要： | 提出一种包含非线性组件的场线耦合分析模型,在此基础上建立了包含非线性组件的系统级电磁效应分析方法。采用基于黑箱模型的非线性散射参数对非线性组件进行建模,给出了非线性散射参数的实验提取方法。利用焊接在微带传输线上的并联反向HSMS-282C型肖特基二极管构成非线性器件,并搭建原理性实验系统测量了电磁波辐射下连接在微带线上的该非线性器件输出端口的频谱和功率。实验结果与该分析方法的计算结果相吻合,证明了该方法的有效性和可行性,为系统级电磁效应分析提供了一种有效途径。

| Abstract: | A modeling approach for electromagnetic field coupling to a microstrip line connected with nonlinear component is proposed firstly. On this basis, a system-level analysis method of electromagnetic effects on an electronic system containing nonlinear components is presented. Nonlinear scattering parameters based on a black-box model are used to represent the nonlinear behavior of components, and can be extracted from measurement. Finally, the proposed method is experimentally validated by a laboratory system including a simple nonlinear component, which is constituted by the anti-paralleled HSMS-282C Schottky diodes pair welded to a 50 microstrip line. The calculated results using the proposed method show good agreements with the measured data. |
