Title (EN) RF TRANSMITTER AND METHOD OF OPERATION
(FR) EMETTEUR R.F. ET SON PROCEDE DE FONCTIONNEMENT
Abstract: front page image
(EN)An RF transmitter (200) including means (201) for generating a multi-carrier modulation signal comprising a plurality of sub-carriers, means (309) for modulating an RF carrier signal (c(t)) with the sub-carriers of the multi-carrier modulation signal to produce a modulated signal, a signal splitter (305) to split a signal including the sub-carriers of the multi-carrier modulation signal into a plurality of sub-signals each including a sub-set of the plurality of sub-carriers, a plurality of power amplifiers (203) each operable to amplify a separate one of the sub-signals to produce an amplified sub-signal and an RF power combiner (205) operable to combine the amplified sub-signals for transmission as a combined amplified RF signal. Also described is a method of operation of the transmitter.
(FR)L'invention concerne un émetteur R.F. (200) comprenant un organe (201) permettant de générer un signal de modulation multiporteuse composée d'une pluralité de sous-porteuses, un organe (309) permettant de moduler un signal de porteuse R.F. (c(t)) à l'aide des sous-porteuses du signal de modulation multiporteuse afin de produire un signal modulé, un séparateur de signal (305) permettant de séparer un signal comprenant les sous-porteuses du signal de modulation multiporteuse en une pluralité de sous-signaux, chacun d'eux comprenant un sous-ensemble de la pluralité de sous-porteuses, une pluralité d'amplificateurs de puissance (203), chacun d'eux fonctionnant afin d'amplifier l'un des sous-signaux séparés afin de produire un sous-signal amplifié et un combineur de puissance R.F. (205) fonctionnant afin de combiner les sous-signaux amplifiés pour les émettre sous forme d'un signal R.F. amplifié combiné. L'invention concerne également le procédé de fonctionnement de l'émetteur.
