Abstract
By carefully analysis measured data of power amplifier, this paper presents three new models. Model A uses Saleh function in traditional orthogonal bandpass model to increase accuracy. Model B uses an inverse tangent function to model RF power amplifier´s AM-AM nonlinear behavior. Model C uses inverse tangent function in traditional orthogonal bandpass model to model power amplifier´s AM-AM and AM-PM nonlinearity. Emulation shows that each model has its features, and model C gives the best performance.
