Patent ID: 8570104

Claim:
An amplifier assembly for an initial signal having an amplitude and an initial frequency, comprising: an input signal determiner configured to: receive the initial signal and determine a first input signal and a second input signal based on the initial signal, feed the first input signal to a first amplifier that amplifies the first input signal to form a first output signal, feed the second input signal to a second amplifier that amplifies the second input signal to form a second output signal, wherein the first and second output signals have the same amplitude, and have a phase offset with respect to one another, relative to the initial frequency, which is dependent on the absolute value of the amplitude of the initial signal, wherein the first and second amplifiers are configured to feed their respective first and second output signals to a common coupling element, wherein the common coupling element is configured to form a useful signal and a loss signal based on the first and second output signals, such that: a total power including a partial power of the useful signal and a partial power of the loss signal is independent of the phase offset of the first and second output signals, the partial power of the useful signal has a maximum corresponding to a predetermined value of the phase offset of the output signals, and the partial power of the useful signal decreases with a deviation of the phase offset of the first and second output signals from the predetermined value, wherein the coupling element is further configured to feed the useful signal to a load and feed the loss signal to a rectifier device, wherein the rectifier device is configured to rectify the loss signal and feed the rectified loss signal to a power supply device of the amplifier assembly, and wherein the rectifier device includes active components as rectifier elements, wherein the active components are controlled synchronously with respect to the initial frequency.
