Abstract
A power amplifier system includes: a drive stage configured to amplify an RF input signal and implemented in a substrate containing silicon; a power stage including a carrier amplifier configured to amplify a base signal from the RF input signal as amplified by the drive stage, and a peaking amplifier configured to amplify a peak signal from the RF input signal as amplified by the drive stage, the power stage being implemented in a substrate containing gallium arsenide; and a phase compensation circuit configured to change a phase of the RF input signal, wherein either the carrier amplifier or the peaking amplifier is connected to the phase compensation circuit.
