Title (EN) 90-DEGREE LUMPED AND DISTRIBUTED DOHERTY IMPEDANCE INVERTER
(FR) INVERSEUR D'IMPÉDANCE DE DOHERTY GROUPÉ ET RÉPARTI À 90 DEGRÉS
Abstract:
(EN) Apparatus and methods for a modified Doherty amplifier operating at gigahertz frequencies are described. The combining of signals from a main amplifier (132) and a peaking amplifier (138) occur at a combining node prior to impedance matching of the amplifier's output to a load. An impedance inverter (410) comprises a first integrated distributed inductor and a second integrated distributed inductor connected by a capacitor (580), wherein the impedance inverter (410) is connected between an output of the main amplifier (132) and the combining node.
(FR) L'invention concerne un appareil et des procédés pour un amplificateur de Doherty modifié fonctionnant à des fréquences de l'ordre du gigahertz. La combinaison de signaux provenant d'un amplificateur principal (132) et d'un amplificateur (138) de crêtes a lieu au niveau d'un nœud de combinaison avant l'adaptation d'impédance de la sortie de l'amplificateur à une charge. Un inverseur (410) d'impédance comporte un premier inducteur réparti intégré et un deuxième inducteur réparti intégré reliés par un condensateur (580), l'inverseur (410) d'impédance étant branché entre une sortie de l'amplificateur principal (132) et le nœud de combinaison.
