Abstract
The method for system level oriented load-pull-based envelope tracking power amplifiers includes steps of performing a multi-dimensional load-pull and selecting the reflection coefficients to be presented to the transistor while taking into account the system level architecture of the power amplifier. It is shown that adopting the proposed load reflection coefficient selection algorithm leads to an additional efficiency enhancement. This extra performance is achieved without additional circuitry or cost.
