ABSTRACT:
A power amplifier system, a control method thereof, and a control device thereof are provided. The power amplifier system operates in a non-linear switching mode according to an envelope amplitude of an input signal under control of the control device. When the power amplifier is operated in the non-linear switching mode, a supply voltage and an input signal of the power amplifier are provided to the power amplifier by the control device according to pre-measured properties of the power amplifier so as to equip the power amplifier with a high power-added efficiency (PAE) and a better linearity.
