The present invention relates to arrangements and methods for radio frequency modulation and power amplification of an information signal (X IF). Modulation and amplification of the information signal (X IF) is carried out with very high linearity and efficiency over a wide frequency band by sigma-delta modulating (410) said information signal (X IF), whereby a digital signal (Y) is generated. The digital signal (Y) is up-mixed and voltage switched (420) by voltage-fed switches (423) controlled by the up-mixed digital signal (RF). Said switches are preferably conductive elements whose electric conductivity depend on the amount of ionising radiation that falls on the elements.
La présente invention concerne des agencements et procédés destinés à moduler la radiofréquence et amplifier la puissance d'un signal d'informations (XIF). Cette modulation et cette amplification du signal d'informations (XIF) s'exécutent avec une très grande efficacité et linéarité, sur une large bande de fréquences, par modulation delta-sigma (410) dudit signal (XIF), produisant ainsi un signal numérique (Y), lequel est mélangé avec multiplication en fréquence puis commuté en tension (420) au moyen de commutateurs alimentés en tension (423) et commandés par le signal numérique mélangé (RF), ces commutateurs étant de préférence des éléments conducteurs dont la conductivité électrique dépend de la dose de rayonnement ionisant incidente sur ces éléments.
