PURPOSE:To reduce leakage inductance by winding primary and secondary windings so that they are generally placed one above the other in shape, thereby raising the coupling factor. CONSTITUTION:After a secondary winding 2 and a primary winding 1 are sequentially inserted into the winding groove 5 in a lower magnetic core 3 and fixed, an upper magnetic core 4 is fixed, and the terminal of the secondary winding 2 is soldered to the copper foil terminal 7 of a terminal assembly 6, thereby constructing a step-up transformer. The respective windings 1, 2 in the winding groove 5 are constructed so that the wire width of the primary winding 1 and that of the secondary winding 2 are substantially equal. This can significantly improve the coupling factor. As a result, leakage inductance greatly decreases, and thus the step-up ratio of the step-up transformer can be raised, thereby improving the transformer efficiency. |

PURPOSE:To obtain a transmission device having various passing bands by such an arrangement wherein a ferrite calcined body of high magnetic permeability and that of low permeability are arranged in layers and integrated together and at least one piece of conductor is embedded therein, and the magnetic permeability, thickness, size, relative arrangement, relative dimension, etc. of the calcined body are properly selected.

Magnetic devices, and associated methods of manufacture, using flex circuits. Conductive flex circuit traces, or combinations of such traces with conductive printed circuit board or other substrate traces, form windings around toroidal ferromagnetic cores. Bending the flex circuit into a partial loop or a full loop forms partial or full windings respectively. Bonding or flow soldering electrically connects the windings together and to a printed circuit board or other substrate. The methods yield transformers with high conversion efficiency, are compatible with conventional printed circuit boards and readily available high-volume assembly equipment, and avoid the higher cost of manually made windings. |

Provided is a transmission line transformer having increased signal efficiency. The transmission line transformer is formed on an integrated circuit (IC), wherein a first transmission line disposed in one direction. Second and third transmission lines have same length direction as the first transmission line and are spaced apart from each other in a lateral direction above or below the first transmission line. Accordingly, an area of the first transmission line and areas of the second and third transmission lines, which face each other, are increased, thereby improving a coupling factor. Also, since a secondary transmission line is divided into two regions and uses the second and third transmission lines that have narrower widths than the first transmission line, parasitic capacitance components generated between the first through third transmission lines and a semiconductor substrate may be decreased. |
