description The invention relates to a high-linearity radio frequency power amplifier, which comprises an amplifying circuit and a biasing circuit, the biasing circuit comprises more than two self-adaptive linearization biasing circuits, and each self-adaptive linearization biasing circuit is connected with a corresponding control power supply and is connected with the amplifying circuit; and the respective adaptive linearization bias circuits are configured with different circuit parameters. More than two self-adaptive linearization bias circuits with different circuit parameters are configured for the amplification circuit, dynamic adjustment of linearity indexes of the radio frequency power amplifier can be realized only by adjusting the size and ratio of the control power supply corresponding to each self-adaptive linearization bias circuit, and the radio frequency power amplifier is simple in structure, convenient to control and low in cost. And the design and debugging efficiency of the high-linearity radio frequen
