摘要：
Embodiments of RF power amplifiers are disclosed that include switched-mode power amplifiers supplied by synchrnous buck DC-DC converters. The switched-mode power amplifiers can be used to amplify a limited form of an RF input signal and the supply to the switched-mode power amplifier is varied in response to the envelope of the RF input signal. One embodiment includes a switched-mode power amplifier connected to a synchronous buck DC-DC converter.
