摘要
为了使学生深入理解功率放大器(功放)的非线性特性对信号传输的影响,将共享功放线性化平台引入射频电路课程实验教学,将抽象难懂的非线性理论以及线性化过程转化为可视化实验,旨在提高学生的学习积极性,提升教学效果。该文对预失真模块、线性化系统、共享平台搭建以及测量实例等进行了具体分析和讲解,希望有助于学生对射频电路实际应用的理解和掌握。
In order to enable students to understand the effect of nonlinearities of power amplifiers on transmitted signals, the sharing linearization platform for power amplifiers can be introduced to experimental teaching in the course of radio frequency(RF) circuit design, transforming the abstract nonlinear theory and linearization approaches into visualized demonstrations, so as to improve the students’ enthusiasm and teaching effectiveness. It elaborates the predistortion module, linearization system, construction of sharing platform and measurement example, which is helpful for students to understand and master the practical application of RF transmission system.
