A frequency-hopping arrangement comprises a basic-frequency branch (DIV1), an offset-frequency branch (DIV2, DIV3, SCC), and a controllable frequency converter (SBM, FSC). The basic-frequency branch (DIV1) receives an oscillator signal (OS) having an oscillator-signal frequency (7920 MHz). The basic-frequency branch has a frequency-division factor (/2) so as to provide a basic-frequency signal (BF) having a basic frequency (+3960 MHz) that is the oscillator-signal frequency divided by the frequency-division factor. The offset-frequency branch (DIV2, DIV3, SCC) receives the same oscillator signal (OS). The offset-frequency branch has a different frequency-division factor (/3, /5) so as to provide an offset-frequency signal (OF) having an offset frequency (+528 MHz) that is the oscillator-signal frequency divided by the different frequency-division factor. The controllable frequency converter (SBM, FSC) provides a frequency-hopping signal (FHS) having a frequency (cl*+3960+c2*+528 MHz) that is a linear combination of the basic frequency and the offset frequency with at least one coefficient (c2) that varies as a function of a hopping-control signal (HCS).
