Abstract
A transmitter for a plurality of carriers of a broad-band transmitting spectrum which contains a broad-band power amplifier encompassing the carriers for amplifying an input signal into a more powerful output signal, wherein a measuring signal is formed from the output signal with the aid of a decoupler. The transmitter further contains an adaptation unit for comparing the input signals to the measuring signals and for thereafter forming a correction signal. A predistortion of the input signal is performed in a predistortion unit in the transmitter corresponding to the setpoint selections of the correction signal.
