Abstract

The present invention provides an inductor. The inductor comprises a core substrate; a wire periodically reciprocally laid on the chip substrate by taking a straight line on the chip substrate as an axle wire, wherein the two ends of the wire are respectively provided with leading-out terminals. The technical problems are solved that an inductor uses many magnetic materials for loading, a large induction value cannot be achieved in the broadband application, the core volume is large and the magnetic loss is large in the prior art. The inductor can use few magnetic materials to reduce the high-frequency magnetic loss, can optimize the high-frequency performance, can greatly reduce the inductor size through adoption of a special coiling method, is convenient to integrate, achieves broadbandinduction on the chip and can be suitable for large-scale production.

Description

technical field [0001] The present invention relates to the technical field of inductors, in particular to an inductor. Background technique [0002] Inductance is a property of a closed loop and a physical quantity. When the coil passes current, a magnetic field induction is formed in the coil, and the induced magnetic field will generate an induced current to resist the current passing through the coil. The interaction between this current and the coil The inductive reactance, or inductance, is called electricity, and the device that provides inductance is called an inductor. Among them, broadband inductors can be used in radio frequency, microwave, millimeter wave circuits; radio frequency, microwave, millimeter wave integrated circuits; optical and electrical communication circuits; broadband inductors can be used in broadband amplifiers; can be used in broadband bias-tee; can be used in broadband filter. [0003] However, the applicant of the present invention finds t...
