Power amplification chain i.e. high power amplifier, control device for electronic circuit, has active component delivering input power having value that is less than critical threshold, to power amplification chain

The device (DIS) has an active component i.e. class AB type average power amplifier (AMOP), whose polarization point is a function of a value of power received at its input (EN-AMOP). The component delivers an input power having value that is less than a critical threshold, to a power amplification...

Summary:The device (DIS) has an active component i.e. class AB type average power amplifier (AMOP), whose polarization point is a function of a value of power received at its input (EN-AMOP). The component delivers an input power having value that is less than a critical threshold, to a power amplification chain i.e. high power amplifier (HPA). The component is coupled in upstream of the amplification chain. The component has a resistive element i.e. resistor (R), connected between a supply terminal and the input of the component. L'invention vise un dispositif de contrôle (DIS) d'une chaîne d'amplification en puissance (HPA), ledit dispositif de contrôle (DIS) comprend un composant actif (AMOP) dont le point de polarisation est fonction de la valeur de la puissance qu'il reçoit en entrée, et qui est configuré de façon à délivrer audit amplificateur de puissance (HPA), une puissance d'entrée ayant une valeur inférieure à un seuil critique.
