Claim:
1. A radio frequency power amplifier system comprising: a power amplifier configured to receive a radio frequency input signal, a first supply voltage, and a second supply voltage and to amplify the radio frequency input signal into a radio frequency output signal; and a power supply coupled to the power amplifier, the power supply including a first power converter configured to receive an input voltage and generate a first output voltage and a second power converter configured to receive the first output voltage and generate a second output voltage, the power supply being configured to provide the first output voltage to the power amplifier as both the first supply voltage and the second supply voltage responsive to being in a first mode of operation and to provide the first output voltage to the power amplifier as the first supply voltage and provide at least a portion of the second output voltage to the power amplifier as the second supply voltage responsive to being in a second mode of operation.
