If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: you can ...

For those who enjoy building radio projects, you may have noticed that variable capacitors are not as available as they once were. There was a time when all radio receivers contained at least one, but ...

[Jezan] decided to introduce his son to electronics by building a small crystal radio. These crystal sets have been around for a long time, and make for a great beginner electronics project, but some ...

How do you implement a variable capacitor these days? Mechanical caps are out. That leaves varactors, which work fine but require higher voltages that often are not available, and their response is ...

SAN DIEGO--(BUSINESS WIRE)--Peregrine Semiconductor Corporation, a fabless provider of high-performance radio-frequency (RF) integrated circuits (ICs), today announced availability of the ...

The NCD2100 electronic programmable capacitance IC has a capacitance range of 6.6 to 37.55 pF in small 63-fF steps for shunt configuration. The digitally controlled capacitance trimming setting is ...

The first British commercially available high-vacuum variable capacitors have been announced by the English Electric Valve Co. So 64 years ago, started a story in Electronics Weekly’s edition of March ...

This file type includes high resolution graphics and schematics. Cavendish Kinetics now offers a tunable RF micro-electromechanical systems (MEMS) capacitor that lets smart-phone antennas cover a ...

Marked: "Dayton Fan & Motor Co. / Dayton, Ohio, U.S.A. / Day-Fan". A Variable capacitor with six fixed plates and six movable plates. Arrangement of plates permits interleaving of sets of three each, ...
