Abstract

Carte de circuits imprimés prévue pour être placée dans le logement pour carte d'un ordinateur personnel (102) afin de permettre à ce dernier (102) de recevoir directement des informations transmises par un réseau de télécommunications par satellite. Une carte (124) de périphérique fonctionne en mode asservi par rapport à une unité centrale (120) de l'ordinateur personnel (102). L'unité centrale (120) reçoit des signaux démodulés d'un démodulateur (130) de la carte (124) de périphérique via une interface (134) de bus située sur la carte (124) de périphérique. L'unité centrale (120) reçoit également des informations relatives à l'état du démodulateur (130) et d'un syntonisateur (132) par l'intermédiaire de l'interface (134) de bus. Un convertisseur CC-CC (136) reçoit de la puissance d'une alimentation (126) en puissance pour le circuit de la carte de périphérique. En outre, le convertisseur CC-CC (136) alimente un bloc à faible bruit (BFB 112) d'une antenne (110) du réseau de télécommunications par satellite.
