ABSTRACT POWER AMPLIFIER, POWER AMPLIFICATION METHOD, AND POWER AMPLIFICATION CONTROL APPARATUS AND METHOD Embodiments of the present invention relate to the field of power amplifiers, and provide a power amplifier, a power amplification method, and a power amplification control apparatus and method. The power amplifier includes n Doherty power amplification units connected in parallel and an n-way outphasing combiner, where n≥2 and n is an integer; each Doherty power amplification unit includes one input end and one output end; the n-way outphasing combiner includes n input ends and one output end; and the output ends of the Doherty power amplification units are separately connected to the input ends of the n- way outphasing combiner. In the present invention, by means of the power amplifier having this structure, high efficiency can be maintained within a larger input power changing range, thereby further reducing power consumption.
