MODULATED RADIO SIGNAL TRANSMITTER WITH SELF-ADAPTED AMPLIFICATION POLARISATION

摘要

The invention concerns a transmitter of modulated radio signals (SMS) according to a discrete plurality of amplitude levels, wherein at least each output power transistor (6) receives on one of its terminals, a polarising voltage level adapted to the amplitude level represented by the instantaneous value of a selection signal (SS) produced by analysing means (11) based on digital control signals (1), thereby optimising power consumption.
