Title (EN) STABILIZED HIGH EFFICIENCY RADIO FREQUENCY AMPLIFIER
(FR) AMPLIFICATEUR STABILISE DE FREQUENCE RADIO A RENDEMENT ELEVE
Abstract:
(EN) A high efficiency radio frequency amplifier (50) which includes stabilization circuitry (100) which is selectively actuated during periods of time when undesired amplifier circuit operating conditions are present which tend to cause amplifier oscillation. Otherwise, the stabilization circuit (100) remains in effect decoupled from the amplifier so as not to unnecessarily draw power from the amplifier circuit (50) when its action is not required to prevent undesired oscillation of the amplifier.
(FR) Un amplificateur de fréquence radio à rendement élevé (50) comprend un circuit stabilisateur (100) travaillant de manière sélective pendant les laps de temps où se vérifient des conditions indésirables de fonctionnement du circuit amplificateur qui tendent à provoquer l'oscillation de l'amplificateur. En l'absence de ces conditions, le circuit stabilisateur (100) reste déconnecté de l'amplificateur afin de ne pas tirer inutilement de la puissance du circuit amplificateur (50) lorsque son action n'est pas nécessaire pour empêcher l'oscillation indésirable de l'amplificateur.
