Claim Text:
1. An amplifier system comprising a digital signal component separator configured to split an amplitude and phase modulated signal into a first phase modulated signal and a second phase modulated signal, a non-isolating combiner configured to perform a signal summation of the first phase modulated signal and the second phase modulated signal, a first power amplifier configured to perform amplification of the first phase modulated signal before the signal summation, and a second power amplifier configured to perform amplification of the second phase modulated signal before the signal summation, wherein the amplifier system is configured to apply a signal component separator algorithm such that the first phase modulated signal and the second phase modulated signal are allowed to take on several discrete and/or continuous amplitude levels in order to achieve a maximum efficiency at each desired output signal power level, without restricting the input signal power fed to the power amplifiers to a constant level, wherein for each desired output signal power level, the digital signal component separator assigns an amplitude and phases of input signals that result in a maximum instantaneous power efficiency of the amplifier system.
