A power amplification method and device for an outphase modulation-based power amplifier. The method comprises: decomposing an original input signal into at least two decomposed signals of different amplitudes; amplifying, by at least two power amplifiers (21, 22), powers of corresponding decomposed signals to obtain power-amplified decomposed signals, wherein the number of the power amplifiers (21, 22) is the same as that of the decomposed signals; and synthesizing, by a non-insulation combiner (30), the various power-amplified decomposed signals, to obtain power-amplified output signals, wherein the non-insulation combiner (30) comprises a circuit capable of realizing a vector synthesis formula of different amplitudes. Also disclosed is a device using the method. By means of the method and device, the efficiency of radio signal power amplifiers can be increased. |
