Abstract
Methods and systems for improving digital pre-distortion calibration of a radio frequency power amplifier. The disclosed method includes, among other things, initiating digital pre-distortion calibration of a power amplifier of a radio frequency (RF) module, determining, based on a transmission power of a training signal transmitted to the power amplifier between a first transmission power value and a second transmission power value, a set of estimated coefficients, generating, based on a subset of the set of estimated coefficients, a set of predicted coefficients, wherein the set of predicted coefficients are derived from a fitting curve applied to the subset of the set of estimated coefficients, and storing the set of estimated coefficients and the set of predicted coefficients.
