课程名称：使用史密斯软件进行阻抗匹配的实用示例 课程概述：阻抗匹配的概念相对简单，即使一种阻抗看起来像另一种阻抗的过程。通常，我们需要将负载阻抗与驱动源的源阻抗或内部阻抗匹配。多种元件和电路可用于实现阻抗匹配。该课程借助来自伯尔尼应用科技大学的Fritz Dellsperger教授的史密斯软件，讲解如何通过使用RLC元件、传输线及开路/短路stub等手段将阻抗匹配到所需值。课程适合希望成为射频/硬件工程师的所有工程师。史密斯软件包含了史密斯图，便于我们进行阻抗匹配。软件的功能包括： - 使用电容器、电感器、电阻器，以及串联和并联的RLC和变压器进行匹配梯形网络 - 为史密斯图设置可调的标准化阻抗 - 表示稳定性、噪声系数、增益、VSWR和Q因子的圆圈和轮廓 - 插入后可编辑元件值 - 使用滑块调谐元件值（调谐控制台） - 按频率或数据点进行扫描 - 处理有损的串行传输线 - 将数据点和圆圈信息导出为ASCII文件，以便在电子表格或数学软件中后处理 - 从S参数文件（Touchstone，CITI，EZNEC）导入数据点 - 撤销和重做功能 - 保存和加载设计（仅限授权版本） - 保存网表（仅限授权版本） - 打印史密斯图、原理图、数据点、圆圈信息和S图表 - 复制到剪贴板以供文档使用 - 所有图表的颜色和线宽设置 史密斯软件的商业许可证全功能定价为120美元，大学、学生和持有呼号的业余无线电爱好者可享受80美元的特别价格。
The term "impedance matching" is rather straightforward. It's simply defined as the process of making one impedance look like another. Frequently, it becomes necessary to match a load impedance to the source or internal impedance of a driving source. A wide variety of components and circuits can be used for impedance matching. In this course, with the help of Smith Software from Prof. Fritz Dellsperger (at Bern University of Applied Sciences), we will explain how to match the impedance by using RLC elements, Transmission like, open/short stub to any wanted value.This course is suitable for every Engineer who wants to work as RF/Hardware Engineer. Smith Software contains Smith Chart, which facilate the process for impedance matching for us. Smith chart contains below capabilities in the software.
