1. A device for emitting and/or receiving signals in at least two symmetrical frequency bands in relation to a first central frequency of symmetry FCA and such that each one of the at least two frequency bands comprises at least two channels, or groups of channels, symmetrical in relation to second central frequencies of symmetry, including a central lower frequency FCLA, and a central upper frequency FCUA, said device comprising at least:
a first circuitry able to generate a periodic signal of frequency FA, a periodic signal of frequency FB=FA/N1, a periodic signal of frequency F1 equal to |FCA−FCLA| and a periodic signal of frequency F2 equal to the difference between a central frequency of one of the at least two channels or groups of channels and the second frequency of symmetry associated with said one of the at least two channels or groups of channels, and wherein
FA=N1·(FCLA+F1)/(N1+1) with N1 being a number greater than 1;
a second circuitry able to carry out a first non-linear operation between the periodic signals of frequencies FA and F1 generating a first multitone signal of which the frequency spectrum comprises two main lines at frequencies FA−F1 and FA+F1, and able to carry out a second non-linear operation between the periodic signals of frequencies FB and F2 generating a second multitone signal of which the frequency spectrum comprises two main lines at frequencies FB−F2 and FB+F2.
