Abstract (en)
[origin: WO2004070943A1] The invention relates to a method for improving the output power of a non-linear power amplifier (1), according to which signal amplitudes of a digital baseband are predistorted and then fed at the input of the power amplifier (1) that is provided with a non-linear characteristic curve in order to linearize the characteristic curve. The invention is characterized by the fact that the signal amplitudes are fed to the input of the power amplifier (1) in a predistorted manner up to a predetermined transition power (8) while being fed to the input of the power amplifier (1) in a non-predistorted manner from said predetermined transition power (8) on.
