Abstract
Disclosed is a method for producing a stage for amplifying the power of a variable envelope signal including at least one amplifier. For each amplifier, a form of ideal variation in average power POUTL is selected. For each value of each setting parameter and for each average input power value, a value of an optimisation criterion is calculated on the basis of the mathematical expectation of at least one optimisation parameter. An optimum value of each setting parameter is determined and the amplification stage is produced with a number of amplifiers in parallel determined on the basis of an average output power value and with, for each amplifier, matching circuits providing the optimum values of the setting parameters. The invention also relates to an amplification stage produced in this manner.
