摘要

描述了一种通用的包络跟踪(ET)发射机，它同时利用驱动和漏极调制。我们开发了一种仿真方法，用于模拟组件非理想性对系统性能的影响，从硬件测量数据开始。示例分析评估ET系统线性度，功率放大器效率和W-CDMA下行链路发射机包络调制器要求之间的权衡。

Envelope tracking transmitter system analysis method

A general envelope tracking (ET) transmitter is described which utilizes both drive and drain modulation. We develop a simulation method useful for modeling the impact of component non-idealities on system performance, starting from hardware measurement data. An example analysis evaluates tradeoffs between ET system linearity, power amplifier efficiency, and envelope modulator requirements for a W-CDMA down-link transmitter.
