A method for amplifying power and a power amplifier, which relates to the technical field of wireless communications, to improve a working bandwidth of a power amplifier. The power amplifier comprises: a power divider, a carrier power transistor, a peak power transistor, a first low order filter and a second low order filter and an impedance matching network, wherein the power divider is respectively connected to the carrier power transistor and an input of the peak power transistor, an output of the carrier power transistor is connected to an input of the first low order filter, an input of the peak power transistor is connected to the second low order filter, an output of the first low order filter is connected to an input of the impedance matching network, an output of the second low order filter is connected to the input of the impedance matching network, and an output of the impedance matching network is connected to a load; and the power amplifier is used for the power amplification of an input signal. |
