An amplifier assembly includes an input signal determiner that determines a first input signal and a second input signal based on an initial signal having an amplitude and an initial frequency. Amplifiers amplify the first and second input signal to form first and second output signals having a phase offset with respect to one another. The first and second amplified output signals are fed to a common coupling element that forms a useful signal and a loss signal, such that a total power of the useful signal and loss signal is independent of the phase offset, the power of the useful signal has a maximum corresponding to a predetermined value of the phase offset, and the partial power of the useful signal decreases with a deviation of the phase offset from the predetermined value. The coupling element feeds the useful signal to a load and the loss signal to a rectifier device that feeds a rectified loss signal to a power supply device, wherein the rectifier device includes active components as rectifier elements, which are controlled synchronously with respect to the initial frequency.
