Abstract
According to one aspect, embodiments of the invention provide an amplifier system comprising a first phase shifter configured to generate, based on an input signal, a first signal and a second signal, the second signal being out of phase with the first signal, a first amplifier configured to apply a first gain to the first signal to produce a gain adjusted first signal, a second amplifier configured to apply a second gain to the second signal to produce a gain adjusted second signal, a second phase shifter configured to combine the gain adjusted first and second signals to produce an output signal, and a controller configured to identify a high voltage swing across the first amplifier and, in response to identifying the high voltage swing, adjust the first gain to reduce output power of the first amplifier and adjust the second gain to increase output power of the second amplifier.
