Abstract

La présente invention concerne un circuit d'entrée pour récepteur VHF. Des signaux d'entrée VHF appliqués à une borne 1 sont sélectivement amplifiés par un amplificateur à haute fréquence 8 et un circuit d'accord connecté à une borne 3. Le signal amplifié est fourni à un mélangeur 9. Un oscillateur local Il est connecté à une autre borne du mélangeur 9, le signal de sortie à fréquence intermédiaire étant fourni à une borne 5. Un circuit de polarisation 10 agit sur le mélangeur 9 et l'oscillateur 11. Application aux récepteurs radio à modulation de fréquence portatifs.
