摘要：A variable load power amplifier that improves the performance of a power
amplifier that provides both envelope tracking (ET) and average power tracking (APT).The variable load power amplifier can include a plurality of amplifiers that are eachselectively connectable into one of a plurality of parallel combinations, each of theplurality of parallel combinations characterized by a corresponding load line. The
variable load power amplifier can also include a plurality of control elements arranged toselectively connect one or more of the plurality of amplifiers into one of the plurality ofparallel combinations, each of the plurality of control elements having a respective inputterminal provided to receive a respective control signal, each of the plurality of controlelements responsive to the respective control signal.
