Abstract
An amplifier for amplifying a radio signal to a defined power output level is presented, wherein the amplifier comprises an amplifier input port, an amplifier output port, a first transistor for amplifying the radio signal received at a first transistor control input, wherein a first transistor output of the first transistor is supplied by a first power source; a at least second transistor for supplying the first transistor from a at least second power supply source. The at least second power supply source is added by the at least second transistor as a function of the power output level of the amplifier.
