综合型模块化高频电子线路实验平台的研制

Development of Comprehensive Modular High-frequency Electronic Circuit Experimental Platform

为加强学生工程实践与创新能力的培养,设计并制作了一套综合型模块化高频电子线路实验平台。实验平台采用模块化设计的思想,分为载波产生、调制波产生、信号调理、调制、高频功放、小信号放大、混频、中频放大、解调和信号输出共10个功能模块。各模块既可独立开展基础型实验,也可级联成高频调制解调收发系统,完成综合型实验。实验平台涵盖了高频电子线路课程的重难点章节,内容丰富,可拓展性强,适合用于本科实验教学、电子设计竞赛和大学生科研等多种场合,具有极大的应用和推广价值。

In order to strengthen the cultivation of students’engineering practice and innovation ability,a comprehensive modular high-frequency electronic circuit experimental platform was designed and produced.The experimental platform adopts the idea of modular design and is divided into ten modules,which are carrier generation,modulation wave generation,signal conditioning,modulation,high-frequency power amplifier,small signal amplification,mixing,intermediate frequency amplification,demodulation and signal output modules.Each module can carry out basic experiments independently,or cascade into a high-frequency modulation and demodulation transmitting/receiving system to complete comprehensive experiments.The experimental platform covers the important and difficult chapters of the high-frequency electronic circuit course,with rich content and strong expandability.It is suitable for undergraduate experimental teaching,electronic design competitions,student scientific researches and other occasions.It has great application and promotion value.
