A frequency synthesizer modulates a signal by directly modulating a signal input to a voltage controlled oscillator (VCO) associated with the frequency synthesizer. The modulation signal has a bandwidth greater than a closed-loop bandwidth of the frequency synthesizer. The frequency synthesizer suppresses...http://www.google.fr/patents/US7535311?utm_source=gb-gplus-shareBrevet US7535311 - Direct wideband modulation of a frequency synthesizer
