  • Miniature directional coupler
    Patent number: 6686812
    Abstract: A layered directional coupler including conductive traces placed along predetermined axes for making contact with main and auxiliary signal lines. The axes are positioned at predetermined angles relative to each other to maximize the area for making contact thereto, which minimizes the size of the directional coupler. Ground planes are used to minimize parasitic coupling between the traces. The main and auxiliary signal lines are provided by inductively coupled juxtapositioned spiral coils which coupling maximize the characteristics of the coupler.
    Type: Grant
