Le VGA IF contrôlé numériquement IDT F1200<\/a> offre un très faible facteur de bruit inférieur à 3,0 dB et une large plage de contrôle de 23 dB à 7 bits de résolution, qui se traduisent par une qualité de service améliorée des stations de base cellulaires. Cette distorsion extrêmement faible permet de disposer d’une dynamique dénuée de parasites (SFDR) qui adapte ce système à une myriade d’applications. En outre, son excellente précision de gain permet aisément de le corriger numériquement, tandis que les impédances d’entrée et sortie différentielles de 200 ohms permettent de l’intégrer en toute transparence dans le trajet du signal RF, ce qui minimise l’effort et le risque de conception.
\n" Notre nouveau VGA IF offre l’excellent rapport signal sur bruit et la faible distorsion requis par la nouvelle génération de récepteurs sans fil, ce qui renforce la position d’IDT et sa capacité à satisfaire les exigences croissantes du marché 4G ", assure Fred Zust<\/a>, directeur général et vice-président de la division Communications d’IDT. " Les dispositifs de synchronisation et les solutions d’interconnexion RapidIO d’IDT nous ont apporté une excellente visibilité et une parfaite connaissance des systèmes pour résoudre les problèmes courants auxquels sont confrontés nos clients. Dans l’alignement de notre méthode de résolution des problèmes au niveau système, l’étape logique de développement suivante était le traitement des signaux RF. Le nouvel IDT F1200 est le premier d’une série de produits de traitement des signaux RF inscrite par IDT à son planning de développement afin de procurer à ses clients la longueur d’avance dont ils ont besoin pour se démarquer de la concurrence.
