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 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 ...

Abstract: This letter presents an analog–digital variable capacitor realized by monolithic integration of barium strontium titanate (BST) ferroelectric material and phase change material (PCM) ...
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 ...
Abstract: This paper reports an innovative and simple method to achieve highly linear capacitance vs. voltage response and large tuning ratio in a parallel-plate MEMS variable capacitor by moving the ...
Any PN junction diode can be used as a variable capacitor in reverse biased mode, as well as in the forward biased mode before the knee voltage. The capacitance is usually very small as the junction ...
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 ...
