| 摘 要： | 随着3G技术的发展,传输速率的提高,新的调制方式的应用,信号的功率峰均比相当高,因此对基站的线性度要求越来越高.传统的AB类、前馈等功率放大器虽能满足线性的要求,但难以满足系统功耗的要求.以Doherty的理论为基础,以ADS为设计工具,采用了功放管双向牵引优化方法提高单管功率放大器效率,通过对晶体管的双向牵引(源牵引...

| Abstract: | As the 3G technology development,the transmission rate rise,new modulation mode application,the signal Peak-to-Average Ratio are better than before,and the linearity demand of base station is higher and higher.The power amplifier with the traditional AB class or the feed-forward can meet linearity demand,but hard to meet the requirements of system's power consumption.In this paper,based on the theory of Doherty,ADS as design tools,an optimal bilateral pull method was used to increase efficiency of the singl... |
