摘要

本文讨论了包络跟踪应用中手机功率放大器(PA)的设计考虑。ET模式效率、增益、线性度和RX波段噪声之间的权衡在手机环境的限制下进行了描述。讨论了一种准f -1 710mhz HBT放大器，其峰值效率提高了5个点。分析了Vcc整形功能的选项，以解决对效率、增益和噪声的影响。最后比较了两种ET系统结构的稳定性。

Envelope tracking power amplifier design considerations for handset applications

This paper discusses handset power amplifier (PA) design considerations for envelope tracking applications. Tradeoffs between ET mode efficiency, gain, linearity, and RX band noise are described within the constraints of the handset environment. A quasi-F-1 710 MHz HBT PA is discussed which improves peak efficiency by 5 points. Options for the Vcc shaping function are analyzed to address the impact on efficiency, gain, and noise. The paper concludes by comparing stability of two ET system configurations.
