Method, apparatus and arrangement for linearizing of a transmitter array having a plurality of non-linear branches for transmitting into a predetermined direction, wherein the non-linear branches may purposively be made different to obtain varying responses of the non-linear branches over the transmitter array. A combined array response is determined via a feedback structure that models an array response to the predetermined direction and predistortion coefficients are determined based on the measured array response. A feedback circuit with a plurality of feedback branches can be used for feeding back individual response signals at the outputs of the non-linear branches through phase shift and attenuation units of the feedback branches, and for combining the response signals at the outputs of the feedback branches, wherein phase shift and attenuation of each feedback branch is controlled to model a transmission channel of the individual response signals to a receiver in a predetermined direction.
