摘要

包络跟踪(ET)功率放大器(PA)已被开发用于下一代移动电话和平板电脑，以提高效率。ET PA在最高输出功率水平下提供了改进的系统效率，但确实需要考虑性能权衡。本文将讨论ET系统的性能，比较PA技术，并在实现ET PA时提供一些系统性能权衡。

Envelope Tracking power amplifier optimization for mobile applications

Envelope Tracking (ET) power amplifiers (PA) have been developed for next generation mobile handsets and tablets to improve efficiency. The ET PA provides improved system efficiency at the highest output power levels but does require performance trade-offs which must be considered. This paper will discuss the ET system performance, compare PA technologies and will provide some of the system performance tradeoffs when implementing the ET PA.
