A power amplifier system is disclosed. The power amplifier system includes a power amplifier having a first signal input and a first signal output and a main bias circuitry configured to provide a first portion of a first bias signal to the power amplifier through a first bias output coupled to the first signal input. Further included is peak bias circuitry that is configured to provide a second portion of the first bias signal to the power amplifier through a second bias output coupled to the first signal input, wherein the first portion of the first bias signal is greater than the second portion of the first bias signal over a first input power range and the second portion of the first bias signal is greater than the first portion of the first bias signal over a second input power range that is greater than the first input power range.
