Abstract
In order to maximise the efficiency of the RF amplifier located in a transmitter, for instance in both analog and digital terrestrial TV links, it is forced to work near saturation thus introducing an undesirable nonlinear effect. A common solution includes a predistortion system before the modulation that compensates as much as possible the posterior nonlinear distortion, in such a way that the overall performance of the transmitter results in a linear and efficient amplifier. Polynomial models usually implement the predistortion, but we propose an alternative model based on the Fourier-exponential series that shows better performance in the design stage without a significant increase of the complexity.
