Abstract

L'accoppiatore direzionale di tipo ibrido a microonde a costanti concentrate con uscite in quadratura comprende una coppia di induttanze (L1, L2) in film sottile interposte tra una prima coppia di porte (1, 2) e seconda una coppia di porte (3, 4) e un primo e secondo gruppo di capacità (C1, Cp1, Cp2,; C2, Cp3, Cp4) rispettivamente connesse a dette prima e seconda coppia di porte. Ciascun gruppo di capacità (C1, Cp1, Cp2; C2, Cp3, Cp4) è costituita da un condensatore interdigitato (C1id, C2id) avente una striscia terminale (A8; A10) collegata a una porta (1, 3) di una rispettiva prima o seconda coppia di porte (1, 2; 3, 4) e un'altra striscia terminate (A9, A11) collegata all'altra porta (2, 4) della stessa coppia di porte (1, 2; 3, 4). Alle strisce terminati (A8, A9; A10, A11) di ciascun condensatore interdigitato (C1id; C2id) sono collegate rispettive pluralità (8, 9; 10, 11) di elementi a dito alternati tra loro.(Fig. 2).
