| 中文摘要: |
| 阻抗匹配电路的设计是射频实验教学中重要的组成部分。本文以高频地波雷达接收机中匹配电路的设计为原型,设计了一个阻抗匹配的教学实验。该实验要求学生根据项目实际应用需求,针对雷达接收机中具体匹配要求,以ADS仿真软件为设计平台,来完成接收机中滤波器与放大器间的匹配电路的设计。该实验项目将理论分析、电磁仿真与工程应用紧密结合,增强学生对阻抗匹配的原理及其在工程中的具体应用的理解,同时增强学生解决实际工程问题的能力。 |

| The design of impedance matching circuit is an important part of RF experiment teaching. In this paper, an impedance matching experiment is set up based on a matching circuit in the actual project-HF ground wave radar. This experiment requires students to complete the design of the matching circuit between the filter and the amplifier in the receiver based on the actual application requirements and the specific matching requirements of the radar receiver, using ADS simulation software as the design platform. This experiment closely integrates theoretical analysis, electromagnetic simulation and engineering applications to enhance students" understanding of the principle of impedance matching and its specific applications in engineering, and also enhance students" ability to solve practical engineering problems. |
