    Publication number: 20140132343
    Abstract: The invention provides a power amplifier (300) arranged to receive an input power signal (Pin) at an input port of a three port Input Power Splitter, IPS. The IPS is arranged to deliver a main input power signal (P1) to a main amplifier branch and an auxiliary input power signal (P2) to an auxiliary amplifier branch. The power amplifier (300) is arranged to deliver an output power signal (Pout) to a common node. A Phase Compensation Network, PCN, is arranged in the main amplifier branch. A Nonlinear Driver Amplifier, NDA, is arranged in the auxiliary amplifier branch. The NDA is arranged to increase the gain in the auxiliary amplifier branch. The invention also provides a corresponding method and a node in a wireless communication system comprising the power amplifier.
