Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Also known as a trimmer capacitor, these are designed for fine adjustments or calibration in RF Circuits providing the ability to vary capacitance, allowing precise tuning and optimisation of ...

Advanced Energy Industries has been granted a patent for a variable capacitor bank design. The invention includes a conductive housing, electrical bus, and capacitor modules with switched capacitor ...

Abstract: This article presents the implementation of a single-chip silicon-micromachined variable capacitor employing nematic liquid crystal (LC). The LC substance is confined within a slender ...
