    Abstract: Disclosed herein are power amplification (PA) systems configured to amplify a signal, such as a radio-frequency signal. The PA system includes a plurality of power amplifiers that are configured to amplify a signal received at a signal input and to output the amplified signal at a signal output. The power amplifiers are configured to receive a supply voltage that is a combination of a battery voltage and an envelope tracking signal. The PA system includes a PA controller configured to control the power amplifiers based at least in part on the battery voltage or a power output of the power amplifiers. The PA controller can be configured to alter impedance matching components of the PA system to reconfigure a load line of the power amplifiers.
