Abstract: front page image
(EN)A transmitter comprises a baseband processor, a wideband phase modulator and an amplitude modulated amplifier. A signal is provided through the baseband processor and is converted into polar coordinates, comprised of amplitude and phase components, with the amplitude component being transmitted to the amplitude modulated amplifier. The amplitude modulated amplifier being comprised of independently controllable current sources, and with the phase component being transmitted to the wideband phase modulator, for modulation upon a carrier wave, and subsequent transmission to the amplitude modulated amplifier for amplification according to control imposed by the amplitude component upon the current sources.
(FR)L'invention concerne un émetteur comprenant un processeur de bande de base, un modulateur de phase large bande et un amplificateur à modulation d'amplitude. Un signal est fourni par le biais du processeur de bande de base et il est converti en coordonnées polaires comprenant des composants d'amplitude et de phase, le composant d'amplitude étant émis vers l'amplificateur à modulation d'amplitude. Celui-ci comprend des sources de courant à commande individuelle et le composant de phase est émis vers le modulateur de phase large bande, aux fins de modulation sur une onde porteuse et d'émission subséquente vers l'amplificateur à modulation d'amplitude, aux fins d'amplification selon la commande imposée par le composant d'amplitude sur les sources de courant.
