摘要： Embodiments of a variable inductor and a communication device are generally described herein. The variable inductor may comprise a signal wire and a control wire to receive a direct current (DC) control current. The variable inductor may further comprise a magnetic material integrated with the signal wire and the control wire. When a DC control current applied to the control wires takes a first current value, an inductance between an input node and an output node on the signal wire may take a first inductance value. When the DC control current takes a second current value, the inductance between the input node and the output node may take a second inductance value.

摘要： A meandering inductor pattern (4) is formed on the upper surface of an insulating substrate (1). The inductor pattern (4) is formed by irradiating a conductor pattern (2) with a laser beam to form U-shaped trimming grooves (10) in the conductor pattern (2) in such a manner that two island-shape rectangular sections (3) are separated from the conductor pattern.

摘要： An electronic device (10) may include wireless circuitry (24) having a transformer (68) adjustable between first, second, and third modes. The transformer (68) may have first, second, third, and fourth inductors, L1-L4. The third inductor L3, may be magnetically coupled to the first and second inductors L1, L2, with equal coupling constants. The fourth inductor L4 may be magnetically coupled to the first and second inductors L1, L2 with inverse coupling constants. First and second adjustable capacitors C3, C4 coupled to the third and fourth inductors L3, L4 may receive control signals that place the transformer (68) into a selected one of the first, second, or third modes. In the first mode the transformer (68) exhibits a passband that overlaps first and second bands. In the second mode, the transformer (68) passes signals in the second band while filtering interference in the first band. In the third mode, the transformer (68) passes signals in the first band while filtering interference in the second band.

摘要： An electromagnetic induction device, comprising a magnetic coating (110) and at least one set of coils (120). The magnetic coating (110) is formed by splicing all magnetic cells together, and is provided therein with at least one cavity. Magnetic division surfaces (AA) between each two magnetic cells are substantially arranged along a magnetic flux loop without cutting off the magnetic flux loop. The coils (120) are placed in a cavity formed by the magnetic coating (110), and the magnetic flux loop in the magnetic coating (110) is formed by the coils (120) after being energized. The overall structure of the magnetic coating (110) comprises at least two magnetically permeable layers (110', 110"). The electromagnetic induction device, on the one hand, can be substantially closed to reduce leakage flux; on the other hand, since there is no air gap on a magnetic unit, the magnetic reluctance is effectively reduced. In addition, the magnetic coating (110) is of a layered structure so that the electromagnetic induction device can be fabricated in a superposed manner, thereby not only reducing the manufacturing difficulty, but also facilitating obtaining a high-performance flat electromagnetic induction device. Also provided is a corresponding method for manufacturing the electromagnetic induction device.

摘要： The invention relates to a use of a superconductor component in thin layers as a variable inductance. The invention further relates to devices permitting such a use and a method for control of the inductance of such a component. The superconducting inductive component comprises a stack of thin layers of, alternately, electrical insulating material and superconducting material. The inductance thereof varies as a function of the current passing through the same, as part of an alternating current, or by injection of a direct current, superimposed on an alternating current.

摘要： The invention relates to thin-layered superconductors, particularly those having tunable or adjustable characteristics. The invention also relates to a method for the production of said components, in addition to devices including said components. The invention comprises a stack of thin layers alternately consisting of an electrically insulating material and a superconductor material, and tuning means resulting in a resistive link between at least two of said superconductor layers. The inductance of the component can be adjusted by modifying the resistivity of the link.

摘要： Ring-shaped moving holes (2a to 2d) are formed on a first supporting member (2), and holes (4a to 4d) are formed on a second supporting member (4). A first coil (1) is rotated along the moving holes (2a to 2d) in a state where supports (5a to 5d) and bolts (6a to 6d) are inserted in the moving holes (2a to 2d) and the holes (4a to 4d). The first coil (1) and a second coil (3) are fixed so that coil surfaces of the first coil (1) and the second coil (3) become parallel by using the supports (5a to 5d), the bolts (6a to 6d), and nuts (7a to 7d).

摘要： On-chip integrated variable inductors, methods of making and tuning an on-chip integrated variable inductor, and design structures embodying a circuit containing the on-chip integrated variable inductor. The inductor generally includes a signal line configured to carry an electrical signal, a ground line positioned in proximity to the signal line, and at least one control unit electrically coupled with the ground line. The at least one control unit is configured to open and close switch a current path connecting the ground line with a ground potential so as to change an inductance of the signal line.
