The inside of classic radios holds wonders that the sterile chips and SMD components of today’s circuits can’t hold a candle to. Chunky resistors and capacitors, vacuum tubes with cathodes aglow, and ...

Philips’ researchers have micromachined electrically variable RF capacitors. The devices, which are the microscopic equivalent of air-spaced variable and switchable capacitors, can be integrated into ...

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 ...

The Reno GenMatch™ integrates the company’s proven solid-state Electronic Variable Capacitor (EVC™) RF match and Precis™ generator technologies into a single unit. The Reno GenMatch™ integrates the ...

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 ...

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 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 ...

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 ...

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, ...

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 ...
