ABSTRACT:
A power amplifier circuit includes: a transformer receiving a first signal and generating a transformed signal from the first signal; and a transistor receiving a second signal having a direct current (DC) component, and generating an output signal. The second signal and the transformed signal are mixed, via a terminal connected with the transformed signal, wherein an envelope of the output signal is controlled by the first signal.
