Title (EN) METHOD AND APPARATUS FOR EFFICIENT SIGNAL POWER AMPLIFICATION
(FR) PROCEDE ET APPAREIL D'AMPLIFICATION EFFICACE DE LA PUISSANCE DE SIGNAUX
Abstract:
(EN) An apparatus (100) uses power recovery from a combining circuit (125) to improve efficiency. A power combiner (125) generates multiple output signals (127, 133) from a combination of input signals (113, 114). One of the output signals from the power combiner is coupled to a power recovery circuit (135), and energy is recovered and preferably stored for later use.
(FR) L'invention concerne un appareil (100) utilisant la récupération de puissance d'un circuit combinateur (125) pour améliorer l'efficacité. Un combinateur (125) de puissance fournit plusieurs signaux de sortie (127, 133) à partir d'une conbinaison de signaux d'entrée (113, 114). L'un des signaux de sortie fourni par le combinateur de puissance est couplé à un circuit (135) de récupération de puissance, et de l'énergie est récupérée puis de préférence stockée pour utilisation ultérieure.
