Abstract

a. L'invention concerne un système duplex de radiocommunications en micro-ondes. b. Dans un système à postes mobiles et/ou fixes, possédant une branche d'emission comportant une entrée de modulation I et un oscillateur à micro-ondes 3, commun pour la branche d'émission et pour la branche de réception, et une branche de réception comportant un étage mélangeur à micro-ondes 5, un démodulateur 6 et une sortie de modulation II, lesdites branches sont raccordées à un circulateur 7 dont un bras est relié par un coupleur à 3 dB 8 à deux antennes 9, 10 décalées de 180 degrés et il est prévu un circuit de stabilisation 4 pour l'oscillateur à micro-ondes. c. Application notamment à la commande automatique des trains.
