摘要
The microwave hybrid directional coupler with concentrated constants and quadrature outputs comprises a pair of inductances (L1, L2) of thin film placed between a first pair of gates (1, 2) and a second pair of gates (3, 4) and a first and a second group of capacitances (C1, Cp1, Cp2; C2, Cp3, Cp4) connected to said first and second pairs of gates respectively. Each group of capacitances (C1, Cp1, Cp2; C2, Cp3, Cp4) consists of an interdigitated capacitor (C1id, C2id) having a terminal strip (A8; A10) connected to a gate (1, 3) of a respective first or second pair of gates (1, 2; 3, 4) and another terminal strip (A9, A11) connected to the other gate (2, 4) of said pair of gates (1, 2; 3, 4). At the terminal strips (A8, A9; A10, A11) of each interdigitated capacitor (C1id; C2id) are connected respective pluralities (8, 9; 10, 11) of finger elements mutually alternated. IMAGE
