<p>A compact coil for a high performance filter is provided to supply filtering and diplexing functions in a footprint and a compact coil structure. A compact coil for a high performance filter includes three coils(84,86,88). The coils are deposited on the substrate. A first coil is horizontally extended across the substrate while maintaining a vertical side of a plate. A second coil is magnetically coupled to the first coil. A part of the second coil is directed to an inner part of the first coil. A third coil is magnetically coupled to the first and second coils. A part of the third coil is directed to an inner part of the second coil. The coils include first, second, and third ends(90,92,94) respectively. The first end is positioned at 90 degrees from the second end. The second end is positioned at 90 degrees from the third end. The third end is positioned at 180 degrees from the first end.</p> |
