Abstract
A radio-frequency power amplification circuit includes: a power amplification sub-circuit and an output matching sub-circuit, wherein the power amplification sub-circuit is used for selecting, according to a received control signal corresponding to a radio-frequency mode, a power amplification parameter corresponding to the radio-frequency mode to amplify a received radio-frequency signal, and outputting the amplified radio-frequency signal; the output matching sub-circuit is connected to the power amplification sub-circuit and is used for receiving the amplified radio-frequency signal, and transmitting, according to the control signal, the amplified radio-frequency signal by using an impedance corresponding to the radio-frequency mode.
