射频简称RF。射频电路是指工作频率处于30MHz至300GHz的模拟电路。由于其工作频率很高，处理信号的电磁波长与电路或器件尺寸处于同一数量级，必须考虑波动效应。由于器件和导线尺寸的关系，电路需要用分布参数的相关理论来分析与设计。射频电路是无线通信和雷达系统中非常常见的前端电路，其性能很大程度上决定了通信和雷达系统的性能。

“射频电路课程设计”是电磁场与微波技术方向的本科专业课程，以实践为主，旨在向信息工程和电子科学与技术专业的本科生讲授射频电路的相关知识，并通过学生的自我实践初步掌握一些射频电路的分析、设计与实现方法。本课程主要讲授内容包括：射频电路系统的基本架构和特点、射频无源元件、射频有源电路、主流射频电路设计工具、常用射频电路测试仪表及其工作原理等。学生实践课题除上述内容还包括与射频电路密切相关的天线设计和简单无线系统。

Radio frequency is referred to as RF. The RF circuits are the analog circuits with their operating frequency between 30 MHz and 300 GHz. Because of its high operating frequency, the electromagnetic wavelengths of processed signal are of the same order of magnitude as the circuit or device sizes, and the wave effect must be considered. Due to the sizes of devices and lines, the circuits need to be analyzed and designed with the relevant theory of distributed parameters. RF circuits are very important front-end circuits in various wireless communication and radar systems, and their performance largely determines the performance of communication and radar systems.

This course of "RF Circuit Design" is an undergraduate course in the electromagnetic fields and microwave technologies. It is based on practice and aims to teach the relevant knowledge to undergraduate students major in information engineering and electronic science and technology. Mainly through the students' self-practice, they should master the analysis, design and implementation of some RF circuits. The main contents of this course include: the basic architecture and characteristics of RF circuit systems, RF passive components, RF active circuits, mainstream commercial software for RF circuit design, common instrumentations of RF circuit testing and their working principles. In addition, the topics of student practice include antenna design and simple wireless systems that are closely related to RF circuits.
