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 ...
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 ...
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 ...
Recently Cavendish Kinetics, a MEMS (Micro-Electro-Mechanical-Systems) design house, issued a press release announcing a partnership with TowerJazz to produce tunable MEMS capacitors for use in mobile ...
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 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 ...
Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...
