Tous deux intègrent un démodulateur IQ avec boucle PLL hautes performances, un oscillateur commandé en tension (VCO) à faible niveau de bruit et deux régulateurs à faible chute de tension (LDO). Les démodulateurs ADRF6806 et ADRF6807 sont les seuls démodulateurs en quadrature du marché à combiner trois fonctions RF sur un seul et unique circuit, avec à la clé une conception simplifiée, une réduction de l’espace occupé sur la carte et une baisse du coût en composants. Ils conviennent à un large éventail d’applications de communications large bande, telles que les infrastructures de communications cellulaires ou les liaisons hyperfréquences point à point.
\nCes deux démodulateurs utilisent un cœur de mélangeur hautes performances qui assure des niveaux d’entrée IP3 et d’entrée P1dB exceptionnels, doublés d’un très faible niveau de bruit en sortie et d’une excellente plage dynamique. Le port série SPI permet à l’utilisateur de contrôler la PLL fractionnaire, le diviseur d’oscillateur local (LO) du démodulateur, plusieurs fonctions d’optimisation, le mode basse consommation et l’activation d’un oscillateur local externe. Les démodulateurs ADRF6806 et ADRF6807 sont fabriqués en technologie BiCMOS Silicium-Germanium (SiGe) avancée et disponibles en boîtier LFCSP compact de 6 x 6 mm. <\/p>\n
