The invention relates to an amplifier assembly. The assembly comprises an input device for receiving a representation of an input signal (I, Q; A, phi), a signal-component separator, wherein the signal-component separator produces a first complex intermediate output signal (S) and a second complex intermediate output signal (S), wherein the signal-component separator produces the first complex intermediate output signal (S) and the second complex intermediate output signal (S) on the basis of the representation of the input signal (I, Q; A, phi), wherein the signal-component separator provides a plurality of amplitude levels, wherein the plurality of amplitude levels is selected in such a way that a sum of the first complex intermediate output signal (S) and the second complex intermediate output signal (S) is substantially a reflection of a complex input signal in accordance with the representation of the input signal (I, Q; A, phi) and the phase angle between the first complex intermediate output signal (S) and the second complex intermediate output signal (S) is small. Furthermore, the assembly comprises an amplifying device for amplifying the signals in the high-frequency state and a combining device for combining the signals.
