Abstract
The present invention concerns a composite amplifier and a method for controlling the amplitude of a composite amplifier in a node of a wireless communication system. The composite amplifier comprises a first amplifier and a second amplifier that are arranged to be connected via an output combiner network to a load. The method comprises decomposing an input signal into a first signal component and a second signal component. Further, the method comprises differentiating the amplitude on the first signal component from the amplitude on the second signal component. the differentiation is made such that the aggregated efficiency of the composite amplifier is increased. The present invention also concerns a radio transmission device comprising a composite amplifier.
