Patent ID: 7570930

Claim:
An amplifier arrangement, comprising: a first signal input configured to receive a phase-modulated carrier signal; a second signal input configured to receive a digital amplitude modulation word; an amplifier stage comprising a first connection connected to a reference potential connection, a second connection, and a control connection connected to the first signal input via a filter configured for DC signal suppression; a DC voltage converter comprising a first connection configured to receive a potential, and a control connection configured to receive a control signal, wherein the DC voltage converter is configured to convert the potential into a supply potential, that is variable over a period of time, based on the control signal, and output the supply potential at its output, to the second connection of the amplifier stage; and a digital/analog converter comprising an input connected to the second signal input, and an output coupled to the control connection of the amplifier stage, wherein the digital/analog converter is configured to convert the amplitude modulation word into an analog signal for controlling the amplifier stage.
