ABSTRACT:
Radiofrequency apparatus and method including at least one transmitter and/or receiver of a useful signal S0, at least one device adapted to the application of a coefficient N to the useful signal S0. The method includes modulating the useful signal S0with a frequency Fm, transposing the modulated signal S1to a frequency Fm+Fol, and multiplying the transposed, modulated signal S3by a coefficient N in order to obtain a signal S4at a transmission frequency Fe.
