摘要

本文从三个方面介绍了蜂窝基站功率放大器线性化技术的发展历史。一是降低第二代移动通信系统中多载波基站中功率放大器的饱和输出功率电平。二是降低第三代和第四代移动通信系统中宽带调制载波基站中功率放大器的功耗。第三是减少第五代移动通信系统中Massive MIMO基站中功率放大器的增益和相位偏差。本文从历史演进的角度介绍了我们在蜂窝基站中应用线性化技术的功率放大器研究活动，而线性化技术将不断为新时代蜂窝基站的实现提供新的解决方案。

Linearization Technologies for Power Amplifiers of Cellular Base Stations

This paper presents a historical evolution of linearization technologies for power amplifiers of cellular base stations, which has three aspects. One is to reduce the saturation output power level of power amplifiers in multi-carrier base stations in second generation mobile communication systems. Second is to reduce the power consumption of power amplifiers in wideband modulated carrier base stations in third and fourth generation mobile communication systems. Third is to reduce the gain and phase deviations of power amplifiers in Massive MIMO base stations in fifth generation mobile communication systems. This paper shows our research activities of power amplifiers employing the linearization technologies for cellular base stations with regard to the historical evolution, while the linearization technologies will continuously provide a new solution for realizing the cellular base stations in new era.
