Title (EN) ULTRA LOW PHASE NOISE FREQUENCY SYNTHESIZER
(FR) SYNTHÉTISEUR DE FRÉQUENCE À BRUIT DE PHASE ULTRA FAIBLE
Abstract:
(EN) A system for providing ultra low phase noise frequency synthesizers using Fractional-N PLL (Phase Lock Loop), Sampling Reference PLL and DDS (Direct Digital Synthesizer). Modern day advanced communication systems comprise frequency synthesizers that provide a frequency output signal to other parts of the transmitter and receiver so as to enable the system to operate at the set frequency band. The performance of the frequency synthesizer determines the performance of the communication link. Current days advanced communication systems comprises single loop Frequency synthesizers which are not completely able to provide lower phase deviations for errors (For 256 QAM the practical phase deviation for no errors is 0.4-0.5°) which would enable users to receive high data rate. This proposed system overcomes deficiencies of current generation state of the art communication systems by providing much lower level of phase deviation error which would result in much higher modulation schemes and high data rate.
(FR) L'invention concerne un système permettant d'obtenir des synthétiseurs de fréquence à bruit de phase ultra faible utilisant une boucle à phase asservie (PLL) N fractionnaire, une PLL de référence d'échantillonnage et un synthétiseur numérique direct (DDS). Des systèmes de communication avancés modernes comprennent des synthétiseurs de fréquence qui fournissent un signal de sortie de fréquence à d'autres parties de l'émetteur et du récepteur de manière à ce qu'un système puisse fonctionner dans la bande de fréquence fixée. La performance du synthétiseur de fréquence détermine la performance de la liaison de communication. Des systèmes de communication avancés actuels comportent des synthétiseurs de fréquence à boucle unique qui ne sont pas entièrement capables de fournir des déviations de phase plus faibles pour des erreurs (avec la modulation 256 QAM, la déviation de phase pratique ne donnant pas d'erreurs est 0,4 à 0,5°) permettant à des utilisateurs de recevoir un débit de données élevé. Le système ci-décrit pallie les insuffisances des systèmes de communication de génération actuelle selon l'état de la technique, car il fournit un niveau d'erreur de déviation de phase beaucoup plus faible aboutissant à des systèmes de modulation nettement supérieurs et à des débits de données élevés.
