Abstract: A power amplifier control method is disclosed. A phase modulation control signal may be generated according to an envelope signal that is output by a baseband unit. The phase modulation may be performed on a signal of a main power amplifier link and/or an auxiliary power amplifier link in the Doherty power amplifier circuit according to the phase modulation control signal, so that a phase difference between the signal of the main power amplifier link and the signal of the auxiliary power amplifier link after the phase modulation is a specified value corresponding to a current value of the envelope signal, where the specified value is an optimal phase value of a Doherty power amplifier circuit when the supply voltage of the Doherty power amplifier circuit is an envelope voltage corresponding to the current value of the envelope signal. High-efficiency power amplifier technology is realized.
