Title (EN) DOUBLE BALANCED COMPACT MIXER USING MICROWAVE MONOLITHIC INTEGRATED CIRCUIT COLD FET QUAD
(FR) MELANGEUR COMPACT DOUBLEMENT EQUILIBRE A QUAD DE TECS FROIDS EN TECHNOLOGIE MMIC
Abstract:
(EN) The invention concerns a double balanced mixer with cold FET (11-14) quad (10), comprising couplers at 180° for the quad (10) input/output accesses, said couplers being $g(l)/16 couplers (21, 22) with 3 lines directly coupled in cascade with the quad (10). The invention enables to reduce the space requirement by a factor of 5.4 in Ku-band with respect to the cold FET quad mixer using $g(l)/4 couplers.
(FR) L'invention concerne un mélangeur doublement équilibré à quad (10) de TECs froids (11 à 14). Il comprend des coupleurs à 180° pour les accès entrée/sortie du quad (10), ces coupleurs étant des coupleurs (21, 22) en $g(l)/16 à 3 lignes couplées directement cascadés avec le quad (10). L'invention permet d'obtenir un gain en encombrement d'un facteur 5,4 en bande KU par rapport à un mélangeur à quad de TECs froids employant des coupleurs en $g(l)/4.
