Abstract

Source de fréquences multiples utilisant un oscillateur 10 commandé en tension par une variable indépendante de sélection de fréquence. Selon l'invention, l'oscillateur est stabilisé par une boucle d'erreur qui entraîne un verrouillage de phase automatique de la fréquence sélectionnée (tension de commande 23) sur le plus proche multiple de l'inverse de son temps de transmission dans une ligne à retard à fibre optique 16. Le signal d'erreur est fourni par un détecteur de phase linéaire 18 comparant le signal de sortie de l'oscillateur avec le signal retardé fourni par la voie optique (modulateur 15, fibre 16 et détecteur 17). La stabilité du retard optique permet la multiplication de la fréquence 22 jusqu'au domaine es micro-ondes sans perte de précision, donc l'application de l'invention aux synthétiseurs programmables en hyperfréquence.
