Title (EN) METHOD AND APPARATUS FOR AN IMPROVED POWER AMPLIFIER
(FR) PROCEDE ET DISPOSITIF PERMETTANT D'AMELIORER UN AMPLIFICATEUR DE PUISSANCE
Abstract: front page image
(EN)An amplifier system (52) is provided that has a first balun (48) with an input and an output, and a second balun (18) with an input a an output. A first set of amplifiers (40) is coupled in series and to the output of the first balun (48). A second set of amplifiers (36) is coupled in series and to the output of the second balun. The first and second sets of amplifiers are in series of parallel. A load impedance of the first and second sets of amplifier does not substantially change at an output of any amplifier that is switched on when another amplifier is switched off.
(FR)Cette invention concerne un amplificateur de puissance comportant un premier et un second symétriseurs, tous deux avec une entrée et une sortie. Un premier et un second ensembles d'amplificateurs sont raccordés en série à la sortie du premier et du second symétriseurs, respectivement. Les premier et second ensembles d'amplificateurs sont raccordés en série ou en parallèle. Une impédance de charge du premier et du second ensembles d'amplificateurs n'a pas d'incidence sensible sur la sortie d'un quelconque amplificateur qui est enclenché alors que l'autre est coupé.
