Abstract
A multi-frequency and multi-mode power amplifier is provided. The amplifier has a carrier power amplifier and a peaking power amplifier. The carrier power amplifier receives a first signal and outputs a first amplified signal, in which a first transistor size adjusting unit is included to adjust an equivalent transistor size based on a mode indication signal. The peaking power amplifier receives a second signal and outputs a second amplified signal, in which a second transistor size adjusting unit is included to adjust an equivalent transistor size based on the mode indication signal.
