Abstract
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.
