摘要
An electronic device (ED) is intended for generating a local oscillator signal having a chosen frequency FLO from a main signal outputted by a voltage-controlled oscillator (VCO) and having a fundamental frequency FVCO and harmonics thereof. This electronic device (ED) comprises a frequency division means (D1, D2) arranged to divide the frequency of a signal by a chosen factor N and a filter means (F1, F2) arranged to select a chosen Mth order harmonic of a signal, these frequency division means (D1, D2; D) and filter means (F1, F2) being arranged to process the main signal in common to output the local oscillator signal with a chosen frequency FLO equal to MxFVCO/N.
