Abstract: 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.
