Zusammenfassung:	There is provided a transmitter (61), and a method using such a transmitter, the transmitter having an amplifier (32) for amplifying a received signal, predistortion means (64) for predistorting a received signal prior to the signal passing through the amplifier means, a transmitter for transmitting a signal, and a control (94) for controlling the transmitter. If the power level of the signal to be transmitted by the transmitter is below a predetermined level, the signal is not predistorted by the predistortion means and if the power level of the signal to be transmitted by the transmitter is above a predetermined level the received signal passes through the predistortion means and amplifier.
