Title (EN) RADIO FREQUENCY AMPLIFIER
(FR) AMPLIFICATEUR RADIOFRÉQUENCE
Abstract:
(EN) A modulator circuit is disclosed which comprises a plurality of signal processing branches, each branch comprising a modulator for performing a delta-sigma modulation of a respective data stream portion in order to generate a modulated signal. The modulator circuit receives an input data stream having a carrier frequency; splits the input data stream into a plurality of data stream portions. Delta-sigma modulation is performed in each branch on a respective data stream portion. The respective modulated signals from each branch are combined to form an output signal for outputting at the carrier frequency.
(FR) L'invention concerne un circuit de modulation comprenant une pluralité de branches de traitement de signal. Chaque branche comprend un modulateur pour exécuter une modulation delta-sigma d'un segment de flux de données respectif et générer ainsi un signal modulé. Le circuit de modulation reçoit un flux de données d'entrée ayant une fréquence porteuse, et divise le flux de données d'entrée en une pluralité de segments de flux de données. Une modulation delta-sigma est exécutée dans chaque branche sur un segment de flux de données respectif. Les signaux modulés respectifs, issus de chaque branche, sont combinés pour former un signal de sortie devant être délivré en sortie à la fréquence porteuse.
