Abstract: A radio-frequency power amplifier is supplied by a voltage supply device. The voltage supply device has a voltage divider chain that is connected at the input side with a base potential and a ground voltage. The voltage divider chain has a number of Zener diodes connected in series, with which at least one capacitor is connected in parallel. Intermediate voltages that lie between the ground voltage and the base potential can be tapped at respective node points between each two immediately adjacent Zener diodes. A first supply input of the radio-frequency power amplifier is connected with the ground voltage. The voltage divider chain is connected with the radio-frequency power amplifier via a switching device. The switching device has a number of switching elements connected in parallel with one another, these switching elements being connected at the output side with a second supply input of the radio-frequency power amplifier. The base potential or one of the intermediate voltages is present at the input side of each switching element. The switching elements can be individually controlled by a control device, such that the second supply input can be selectively connected with the base potential and each of the intermediate voltages via the switching device.

Abstract: In a circuit and a method for amplification of an electrical input signal, a signal splitter divides the input signal into a first partial signal in a first signal path and a second partial signal in a second signal path. The first signal path has a first amplification stage for amplification of the first partial signal and the second signal path has a second amplification stage for amplification of the second partial signal. Each of the two amplification stages is supplied with current by a current supply device. Both amplified partial signals are recombined into an output signal by a signal combination element downstream from the amplification stages. The first amplification stage and the second amplification stage are coupled with a regulation device that regulates the amplification of the first partial signal dependent on a current difference between a supply current requirement of the second amplification stage and a supply current requirement of the first amplification stage and which regulates the amplification of the second partial signal dependent on a current difference between the supply current requirement of the first amplification stage and the supply current requirement of the second amplification stage.
