Abstract: A digital radio frequency amplification system including a main amplification channel and distortion correction means including a feedforward correction circuit and a pre-distortion correction circuit, the pre-distortion correction circuit including a feedback loop with a first sampling means for sampling a representative signal from the output of the main amplifier to adapt the pre-distortion and minimize errors at the output of the main amplifier, the main amplification channel being supplied by a signal combining a pure useful signal and a pre-distortion signal, the feedforward correction circuit including a first correction channel supplied by a reference signal and transforming same into a first correction signal, the correction channel constituting with the main amplification channel a first loop including a double coupler for sampling an output signal from the main amplification channel and a combination of the output signal with the first correction signal in order to produce a second correction signa
