Abstract
A power amplifier includes a semiconductor die having a main amplifier and a peaking amplifier. The main amplifier includes at least one first transistor, and the peaking amplifier includes at least one second transistor that is different than the first transistor. The peaking amplifier is configured to modulate a load impedance of the main amplifier responsive to a common gate bias applied to respective gates of the first and second transistors. Related fabrication and methods of operation are also discussed.
