摘　　要：频率变换电路是"高频电子线路"课程的重点和难点之一。本文针对这部分内容提出一项仿真实例设计,给出了仿真电路、仿真结果及分析。在教学中引入Multisim仿真技术,让学生动手绘制电路,选择元器件参数,并进一步分析各参数变化对电路的影响。通过形象生动的波形演示,提高了学生学习兴趣和动手实践能力。The frequency-conversion circuit is one of the most difficult parts in High Frequency Electronic Circuit course. In this paper, we elaborately arrange an example and analysis it detailed based on the Muhisim when the course teaching, we also guide the students themselves to design the circuit based on the Multisim. Then, tougher with students, we further evaluate the performance of the circuit with various parameters. From the simulation resuits, especially the vivid waveform, the students will have an in-depth understanding of the theoretical knowledge. Meanwhile, it will light the learning interesting and improve the practice ability of the students.

关 键 词：高频电子线路 MULTISIM 频率变换 仿真分析
