Accurate Identification of Static Nonlinear Properties of Wideband RF Power Amplifiers

摘要：

In this paper,the dependence of the static nonlinear properties of the wideband RF power amplifiers on the applied signals has been discussed to illustrate the necessity to extract the static nonlinear properties in real time while applying the real modulated signal.A novel dynamic exponential weighted moving average method is proposed to extract the static nonlinear properties of the wideband RF power amplifiers with complicate AM/AM and AM/PM characteristics. The validation results with the measurement data from a 100-watte Doherty LDMOS PA while applying a two-carrier WCDMA signal demonstrate the effectiveness of the novel static nonlinear property extraction method.
