Title (EN) AN ACTIVE LOAD PULL AMPLIFIER
(FR) AMPLIFICATEUR « LOAD PULL » ACTIF
Abstract: front page image
(EN)An active load pull amplifier for amplifying a signal (V) of fundamental frequency (fo) comprising a main amplifier (2); an auxiliary amplifier (3), a 3dB coupled line coupler (9) comprising first and second inputs and first and second outputs; the outputs from the main (2) and auxiliary (3) amplifiers being connected to the first and second inputs of the coupled line coupler (9) respectively; and the 3dB coupled line coupler (9) being a quarter wavelength coupler at frequency fo.
(FR)La présente invention concerne un amplificateur « load pull » actif servant à amplifier un signal (V) de fréquence fondamentale (fo) comprenant un amplificateur principal (2) ; un amplificateur auxiliaire (3) ; un coupleur de ligne (9) couplé à 3dB comprenant une première et une seconde entrées et une première et une seconde sorties ; les sorties depuis les amplificateurs principal (2) et auxiliaire (3) étant respectivement connectées aux première et seconde entrées du coupleur de ligne (9) couplé ; et le coupleur de ligne (9) couplé à 3dB étant un coupleur à quart de longueur d'onde à la fréquence fo.
