Abstract
An amplifier arrangement contains a first signal input for supplying a carrier signal, a second signal input for supplying an amplitude modulation word and an amplifier stage. The amplifier stage is connected to a reference potential connection and, by means of a control connection via a means for DC signal suppression, to the first signal input. A DC voltage converter having a first connection for supplying a potential is designed to convert the potential into a supply potential, which is variable over a period of time, on the basis of a control signal, and outputs the supply potential to the second connection of the amplifier stage. In addition, the amplifier arrangement comprises a digital/analog converter which is coupled to the control connection of the amplifier stage. The input of the converter is connected to the second signal input.
