The invention relates to a method for adjusting the amplification of a high frequency signal, a transmitter or receiver unit and a communication system. The aim of the invention is to provide a method and a device for improved use of a polar-loop concept in a transmitter, especially for a mobile radio link. According to said method for adjusting the amplification of a high frequency signal, wherein the phase angle and the amplitude of an error-free input signal (Usoll) are separated from each other with a defined part of an output signal (Uout) and readjusted, an output voltage (Uc) of a battery voltage modulator (M) is evaluated as a measure for an error at the output of a transmitter amplifier (PA) and taken into account in order to provide a correction. |
