A frequency transposition device is connected to a local main oscillator. The main oscillator is incorporated inside a main phase locked loop whereof the reference frequency is supplied by a voltage-controlled auxiliary oscillator, which is itself incorporated into an auxiliary phase locked loop. The reference frequency of the auxiliary phase locked loop is less than the frequency of the auxiliary oscillator for the main phase locked loop. The reference frequency of the main phase locked loop is less than the output frequency of the main oscillator, is greater than 10 times the frequency spacing of the channels reduced to the output frequency of the main oscillator, and is removed by a whole multiple of the send or receive frequency from at least the cut-off frequency of the main phase locked loop.
A radio frequency device of the type with null or quasinull intermediate frequency, intended to receive or transmit a radio frequency signal whereof the transmit or receive frequency is part of a frequency range subdivided into frequency channels, wherein it comprises on the same electronic chip frequency transposition means connected to a local main oscillator and in that a main oscillator is incorporated inside a main phase locked loop whereof a reference frequency is supplied by a voltage-controlled auxiliary oscillator , itself incorporated into an auxiliary phase locked loop whereof the reference frequency is less than the frequency of the auxiliary oscillator, in that the reference frequency of the main loop is less than the output frequency of the main oscillator, greater than 10 times the frequency spacing of the channels reduced to the output frequency of the main oscillator, and removed by a whole multiple of the transmit or receive frequency of at least the cut-off frequency of the main loop.
