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.
