Abstract

Amplificateur linéaire à faible bruit et oscillateur hyperfréquence commandé en tension construit à partir dudit amplificateur. Chaque amplificateur de l'oscillateur utilise une configuration de transistor à rapport pour générer une sortie linéaire sur une large gamme d'entrée. Le courant de sortie de l'amplificateur est divisé en un courant principal de sortie et des composantes de courant en phase et déphasées à 180~. Une commande d'accord logarithmique combine les composantes des courants en phase et déphasées à 180~ en rapport inverse pour fournir un courant de rétroaction continu constant.
