ELECTRONIC DEVICE FOR GENERATING A LOCAL OSCILLATOR SIGNAL HAVING A FREQUENCY EQUAL TO A FRACTIONAL PART OF A FUNDAMENTAL FREQUENCY.

摘要

An electronic device (ED) is intended for generating a local oscillator signal having a chosen frequency F_L0 from a main signal outputted by a voltage-controlled oscillator (VCO) and having a iundamental frequency F_VCO and harmonics thereof. This electronic device (ED) comprises a frequency division means (Dl, D2) arranged to divide the frequency of a signal by a chosen iactor N and a filter means (Fl ,F2) arranged to select a chosen Mth order harmonic of a signal, these frequency division means (D1,D2;D) and filter means (Fl, F2) being arranged to process the main signal in common to output the local oscillator signal with a chosen frequency F_L0 equal to MxF_VCO/N.
