ABSTRACT:
The invention relates to a power amplifier having a phase amplification path with a phase amplification stage within said phase amplification path. Here the phase amplification stage receives a magnitude component of the power amplified output signal, and the phase amplification stage is responsive to a phase component of the input signal, a magnitude component of the input signal, and the received magnitude component of the power amplified output signal for generating the power amplified output signal. The invention also relates to a power amplifier having a magnitude amplification path for a magnitude component of the input signal with a magnitude amplifier stage within said magnitude amplification path, and with the power amplifier further having a phase amplification path with a phase amplification stage within said phase amplification path.
