ABSTRACT:
A method for improving the output power of a non-linear amplifier, wherein signal amplitudes of a digital baseband are predistorted and then fed at the input of the power amplifier, having a non-linear characteristic curve, in order to linearize the characteristic curve. The signal amplitudes are fed to the input of the power amplifier in a predistorted manner up to a predetermined transition power while being fed to the input of the power amplifier in a non-predistorted manner from the predetermined transition power on.
