Title (EN) AN ULTRA COMPACT MULTI-BAND TRANSMITTER WITH ROBUST AM-PM DISTORTION SELF-SUPPRESSION TECHNIQUES
(FR) ÉMETTEUR MULTIBANDE ULTRA-COMPACT À TECHNIQUES D'AUTO-SUPPRESSION DE DISTORSION AM-PM ROBUSTE
Abstract:
(EN) A communication device includes a power amplifier that generates power signals according to one or more operating bands of communication data, with the amplitude being driven and generated in output stages of the power amplifier. The final stage can include an output passive network that suppresses suppress an amplitude modulation-to-phase modulation (AM-PM) distortion. During a back-off power mode a bias of a capacitive unit of the output power network component can be adjusted to minimize an overall capacitance variation. A output passive network can further generate a flat-phase response between dual resonances of operation.
(FR) L'invention concerne un dispositif de communication qui comprend un amplificateur de puissance qui génère des signaux d'alimentation selon une ou plusieurs bandes de fonctionnement de données de communication, dont l'amplitude est commandée et générée dans des étages de sortie de l'amplificateur de puissance. L'étage final peut comprendre un réseau passif de sortie qui supprime une distorsion de modulation d'amplitude à modulation de phase (AM-PM). Pendant un mode d'alimentation de secours, une polarisation d'une unité capacitive du composant réseau d'alimentation de sortie peut être réglée pour réduire au minimum une variation de capacité globale. Le réseau passif de sortie peut en outre générer une réponse en phase plate entre deux résonances de fonctionnement.
