A method and a device for performing peak power limitation are described. A transmitter stage ( 14 ) according to the invention comprises a distributing component ( 18 ) for distributing the accumulated power of beams or sectors according to a specific distribution scheme among a plurality of power amplifiers ( 26 <SUB>1</SUB> . . . 26 <SUB>4</SUB>). The distributing component ( 18 ) superimposes two or more digital beam or sector signals to generate combined signals which are individually subjected to peak power limitation. The combined signals are then individually subjected to digital predistortion, converted to analog and upconverted to RF. The upconverted RF signals are individually amplified by the plurality of power amplifiers ( 26 <SUB>1 </SUB> . . . 26 <SUB>4</SUB>) constituting a power amplifier pool ( 26 ).
