(FR) EMETTEUR AVEC COMMANDE D'AMPLIFICATEUR DE PUISSANCE
Abstract
(EN)
A mobile transmitter, for use in a cellular radio system, has a power output stage (14) and a voltage supply (30) supplying power to the output stage (14). The voltage supply (30) has a low voltage source (+5V) and a high voltage source (+12V). A switching circuit selectively connects one of the two voltage sources to the output stage (14) in response to a decoder (22) for decoding a digitally encoded demand signal transmitted by a base station.
(FR)
Un émetteur mobile, utilisé dans un système radio cellulaire, possède un étage de puissance de sortie (14) et une alimentation en tension (30) fournissant une puissance à l'étage de sortie (14). L'alimentation en tension (30) possède une source à basse tension (+5 V) et une source à haute tension (+12 V). Un circuit de commutation relie de manière sélective l'une des deux sources de tension à l'étage de sortie (14) en réponse à un décodeur (22) prévu pour décoder un signal de demande codé numériquement et émis par une station de base.
