The invention relates to a kind of linearization method of power amplifier in signal process field, the invention acquires the enveloped spectrum information of nonlinear distorted signal of power amplifier from front feedback signal counteraction loop, and feedbacks then to the input channel of power amplifier through degenerative feedback loop, and superimposes and modulates the enveloped spectrum, with the input signal, and forms the input signal pre-skewness, realizes the linear amplification of power amplifier. The device includes front feedback signal counteraction model, nonlinear skewness enveloped spectrum degenerative feedback model which is the enveloped spectrum information acquired from the front feedback signal counteraction model, and feedbacks it to the input channel of the power amplifier to be modulated into the enveloped spectrum.
