An Envelope Hammerstein Model for Power Amplifiers

  • Author Bio:

Abstract: In this paper, an envelope Hammerstein (EH) model is introduced to describe dynamic input-output characteristics of RF power amplifiers. In the modeling approach, we use a new truncation method and an established nonlinear time series method to determine model structure. Then, we discuss the process of model parameter extraction in detailed. Finally, a 2 W WCDMA power amplifier is measured to verify the performance of EH model, and good agreement between model output and measurement result shows our model can accurately predict output characteristic of the power amplifier.
