The invention relates to a linearization method and an amplifier arrangement, in which a signal (100) to be amplified is predistorted by utilizing digital predistortion information stored in the memory of a predistortion controller (110). Predistortion means (104, 106) predistort the signal (100) to be amplified in its analogue form, the predistortion is adapted at least to the signal (100) to be amplified, the predistortion information stored in the memory of the controller (110) correspond to the variables of polar coordinates, such as phase and amplitude, and the phase and amplitude of the signal (100) to be amplified are distorted in the predistortion in accordance with the predistortion information located in the memory of the controller (110).
