Abstract

La invencion trata de una disposicion de sintonizacion para sintonizar un modulo resonante para aplicaciones inalámbricas, por ejemplo comunicacionesinalámbricas para una estacion base para un sistema de telefonía movil. Comprende el medio paraderiv ar las senales de potencia de entrada y de salida delmodulo resonante. El medio (5) es provisto para obtener las partes portadoras de informacion de las senales de potencia derivadas de cada una para tener unarelacion de ellas. También, elmedio (11) es provisto para sintonizar el modulo resonante hasta que la relacion haya alcanzado un valor mínimo.
