Résumé

A new approach for linear amplification with nonlinear components (Z-LINC) that provides a zero capacitive load to their power amplifiers is proposed. The zero capacitive loading over the whole power back-off range enables to overcome the efficiency deterioration. The concept is theoretically and experimentally validated through a comparative study between fabricated classical LINC and Z-LINC prototypes.

Récepteur électrique

An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power source, such as a battery or generator, which produces power. The term is used more broadly in electronics for a device connected to a signal source, whether or not it consumes power.

Amplificateur audio

Un amplificateur audio est un amplificateur électronique conçu pour amplifier un signal électrique audio afin d'obtenir une puissance suffisante pour faire fonctionner un haut-parleur situé dans une enceinte acoustique ou un casque audio. La source peut être un dispositif d'enregistrement (console de mixage) ou de reproduction (lecteur CD...). Amplificateur électronique La plupart des amplificateurs fonctionnent « à gain fixe », c’est-à-dire que le rapport d'amplification entre le signal d'entrée et le signal de sortie est constant.

Valve amplifier

A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s. Valve amplifiers can be used for applications such as guitar amplifiers, satellite transponders such as DirecTV and GPS, high quality stereo amplifiers, military applications (such as radar) and very high power radio and UHF television transmitters.
