ABSTRACT:
A power amplifier circuit for peak envelope modulation of a high frequency signal is provided. The power amplifier circuit includes a transformer which receives a first signal greater than a predetermined level of an envelope of a carrier signal to generate a transformed signal, and a transistor which operates based on the transformed signal, receives a second signal, which is generated based on the carrier signal and has a direct current component, and amplifies the second signal according to the transformed signal to output an output signal.
