摘要
前馈技术是一种重要的发射机线性化技术。对前馈技术如何实现宽带设计进行了理论分析，在此基础上给出了实际电路的设计，实测结果表明功率放大器的线性度在宽带范围内得到了较好的改善。
Feedforward technique is a popular solution for linearizing transmitters. In this paper, the method of designing feedforward broadband amplifier is analyzed, and a realization of the circuitry is introduced. A careful test is performed, and it shows the PA＇s linearity is improved remarkably on the broadband.
