  • Modulator having little parasitic coupling
    Patent number: 6252472
    Abstract: The present invention relates to a modulator comprising an oscillator which has an oscillation frequency, and a mixer intended to supply a modulated signal with a given output frequency. According to the invention, the nominal oscillation frequency is N times higher than the output frequency, the modulator further including a frequency divider DIV/N intended to receive the output signal of the oscillator and to apply the carrier signal to the mixer, to produce a modulated signal with a first modulation frequency and a parasitic signal with a second modulation frequency.
