The invention relates to a tuning arrangement for tuning a resonance module for wireless applications, e.g. wireless communication for a base station for mobile telephony system. It comprises means for deriving the input and the output power signals of the resonance module. Means (5) is provided for dividing information bearing parts of the derived power signals with each other to have a ratio of them. Also, means (11) is provided for tuning the resonance module until the ratio has reached a minimum value.
L'invention concerne un arrangement de syntonisation pour la syntonisation d'un module de résonance, destiné aux applications hertziennes (par exemple, communications hertziennes de station de base pour système téléphonique mobile). Cet arrangement comprend un système de détermination des signaux de puissance d'entrée et de sortie du module. Un diviseur (5) divise entre elles les partie porteuses d'information des signaux de puissance ainsi déterminés de manière à établir un rapport de ces parties. Enfin, un système (11) assure la syntonisation du module jusqu'au moment où le rapport susmentionné atteint une valeur minimum.
