Abstract (en)
[origin: WO2006105847A1] The invention relates to an improved coupler or power splitter, especially an HF coupler or an HF power splitter, characterised by the following: the four connection lines (13a, 13b; 17a, 17b) are arranged on the same side (3a) of the substrate (3); the two coupling zones (9; 25) are formed on the substrate on two opposite sides (3a, 3b); the second coupling zone (25) is connected to the associated connection lines (17a, 17b) arranged on the side (3a) of the substrate (3) opposing the coupling zone (25), by means of two via holes (21) in an electroplated manner; the capacitors (C-9a, C-9b, C- 9c, C- 9d; C-25a, C-25b, C-25c, C-25d) provided at the beginning (IIa; 18a) and at each end (IIb; 18b) of each coupling zone (9, 25) are respectively embodied as interdigital capacitors; and the capacitors (C-9a, C-9b, C-9c, C-9d; C-25a, C-25b, C-25c, C-25d) are respectively coupled to earth.
