Abstract

The invention discloses an adjustable type built-in inductance element which comprises a dielectric substrate; a first conducting wire arranged on the first surface of the dielectric substrate; a second conducting wire arranged on the second surface of the dielectric substrate and an electrical connector which penetrates the dielectric substrate and is connected with the first conducting wire andthe second conducting wire, wherein, a coupling area is arranged between the first conducting wire and the second conducting wire, and the coupling area comprises a conducting plug connected with thefirst conducting wire and the second conducting wire, or the coupling area comprises an opening arranged in the first conducting wire or the second conducting wire, so as to adjust the inductance value of the inductance element.

Description

technical field [0001] The invention relates to a built-in inductance element, in particular to a built-in inductance element whose inductance value can be adjusted. Background technique [0002] Built-in inductance components have been widely used in circuits such as resonators, filters and matching networks. In the fields of wireless communications, digital computers, portable electronic products, and information appliances, the three characteristics of high frequency, broadband, and miniaturization have almost become the main requirements of high-tech industries and markets. However, when designing high-frequency circuit modules, inductance components are susceptible to coupling and interference from other surrounding lines or components, or are affected by process and material variations, making their inductance characteristics less than expected, which in turn affects the performance of the overall circuit. For example, if an inductance element is placed in an oscillat...
