  • Abstract
    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.
