1. A method for power amplifying an input drive signal to a power amplification system comprising at least three different power amplification modes, wherein each amplification mode is dedicated to operate within a pre-determined amplification interval, said method comprising the step of determining the momentary envelope value (E) of the input drive signal (Sin) (step 1), and the step of:

  • switching amplification mode to one of the at least three amplification modes depending on the determined momentary envelope value (E).
