Abstract
An amplifier comprises a main-amplifier circuit, an auxiliary-amplifier circuit and a signal-generating device. Output terminals of the main-amplifier circuit and of the auxiliary-amplifier circuit are connected according to the Doherty principle. The signal-generating device is configured to generate directly a main-amplifier signal as an input signal of the main-amplifier circuit and an auxiliary-amplifier signal as an input signal of the auxiliary-amplifier circuit.
