Abstract
Methods and apparatus ( ) of amplifying a telecommunication signal ( ) are provided in accordance with the present invention. The apparatus ( ) comprises an input transmission line ( ) configured to receive the telecommunication signal ( ), an output transmission line ( ) configured to provide an amplified output of the telecommunication signal ( ) and N amplifier sections ( ) having a transistor ( ) connected to the input transmission line ( ) and the output transmission line ( ). The apparatus ( ) further comprises a waveform controller ( ) connected to the transistor and also configured to identify a signal level of the telecommunication signal The waveform controller 84 is further configured to generate an independent biasing voltage for the transistor such that the at least one of the N amplifier sections ( ) is configured for active operation and non-active operation based at least in part upon an evaluation of the signal level and an output power of the apparatus is reduced without a substantial degradation in an efficiency of the apparatus.
