Abstract
The present disclosure relates to an amplifier arrangement comprising a first amplifier, a second amplifier and an output combiner arranged to combine respective output signals of the first amplifier and the second amplifier into an output signal of the amplifier arrangement. An amplifier arrangement input signal is arranged as input signal to the first amplifier, and a difference signal, representing a difference between the amplifier arrangement input signal and a scaled output signal of the first amplifier, is arranged as input to the second amplifier. The output combiner is arranged to modulate the loads of the first amplifier and the second amplifier in dependence of the output signal of the second amplifier.
