The present invention relates to a transmitter device arranged for receiving one or more 5 source signals, each containing a sequence of source data symbols. The transmitter device comprises a first predistortion circuit and a second predistortion circuit. The first predistortion circuit comprises at least one correction stage provided with a correction path for determining a correction term. The correction term for each source signal is a function of a corresponding symbol of a predefined constellation for each source signal 10 and of the output of a model. This model comprises a circuit to emulate modulation means and the second predistortion circuit, a circuit to emulate a non-linear transmission link over which a predistorted version of an aggregate pulse-shaped signal is to be transmitted for amplitude levels before saturation of an AM/AM characteristic of the transmission link occurs and to emulate the non-linear transmission link for amplitude levels beyond saturation of the 15 AM/AM characteristic and a circuit to emulate demodulation means. The first predistortion circuit is arranged for adding, for each source signal, the correction term to a digital symbol applied to the first predistortion circuit or to a digital symbol output by a preceding correction stage of the first predistortion circuit.
