摘要
通过了解微波功率放大器的理论知识,研究分析前馈线性化的工作原理,讨论了在设计传统前馈放大器时可能遇到的问题,理论性地提出了一种改进方法。该方法的思想是通过附加一个放大器,来降低对辅助放大器增益要求,使辅助放大器的设计变得容易。
In this paper,the working principle of feed-forward linearity is researched by understanding the theory about the microwave power amplifier.The problem met in designing traditional feed-forward amplifier is discussed.And an improvement is theoretically brought forward.The idea of the improvement is appended an amplifier to reduce the plus requirement of the assistant amplifier.It makes easy to design the assistant amplifier.
