ABSTRACT The process according to the invention consists in breaking down a radiofrequency signal to be modulated according to a first and second signal, representing respectively the sum of the output voltages of identical amplitude of a first and second determined number of modules, with which respectively a first and second vector are associated whose respective amplitude and phase verify that the vectorial sum of the two vectors coincides with a determined reference that is used as a phase reference of the two vectors, in adapting the phase of the load impedance of each module so that vector associated with the current supplied by each of the amplifying modules is in phase delay in relation to their output voltages, in modulating the phase of the two signals by the modulation signal and in adding the first and second phase modulated signal to obtain a resultant amplitude modulated signal. Application: Medium wave radio broadcast transmitters. FIGURE 1
