Patent

CA 2287264

A power amplifier circuit is provided which comprises an input terminal for receiving an input signal and an output terminal for providing an output signal, and at least one transistor for amplifying the input signal to provide the output signal, and means for controlling the input signal received at the input terminal, and means for generating a control signal which substantially follows the temperature of the at least one transistor at least in a selected temperature range. The means for controlling the input signal controls the input signal such that the control signal is prevented from exceeding a predetermined level. The level corresponds to a predetermined temperature of the at least one transistor which is equal to or below a specified maximum temperature for the at least one transistor.

L'invention concerne un circuit amplificateur de puissance comprenant un terminal d'entrée destiné à recevoir un signal d'entrée et un terminal de sortie destiné à fournir un signal de sortie. Le circuit comprend également au moins un transistor permettant d'amplifier le signal d'entrée afin de fournir le signal de sortie, des éléments permettant de commander le signal d'entrée reçu au niveau du terminal d'entrée, et des éléments permettant de produire un signal de commande qui suit sensiblement la température du ou des transistors au moins dans une plage de températures sélectionnée. Le moyen de commande du signal d'entrée commande le signal d'entrée de façon que le signal de commande ne puisse pas dépasser un niveau prédéterminé correspondant à une température prédéterminée du ou des transistors, laquelle est égale ou inférieure à une température maximale spécifiée pour le ou les transistors en question.
