CA 2569387

Systems and methods are provided for efficient amplification of a signal utilizing a modified Doherty amplifier system. A modified Doherty amplifier system includes a nonlinear main amplifier and a nonlinear auxiliary amplifier. An impedance-inverting network separates the main amplifier from an associated load. A second quarter wave transmission line separates the auxiliary amplifier from an associated signal source. The signal source has an associated minimum signal power, such that the signal power never drops below a predetermined percentage of a peak signal power.

Les systèmes et des méthodes ci-présentés assurent l'amplification efficace d'un signal faisant appel à un système d'amplificateur Doherty modifié. Ce système comprend un amplificateur principal non linéaire et un amplificateur auxiliaire non linéaire. Un réseau inverseur d'impédance sépare l'amplificateur principal de la charge associée. Une seconde ligne de transmission quart d'onde sépare l'amplificateur auxiliaire de la source de signal associée. € cette source de signal est associée la puissance de signal minimale, de sorte que cette puissance de signal ne chute jamais en deçà d'un pourcentage prédéterminé de la puissance de signal de crête.
