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 ...

Syfer Technology offers tuning-rod kits based on the company’s Hi-Q range of surface-mount capacitors to help RF design and test engineers select the right capacitor for their circuit or application ...

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 ...

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 ...

Barium strontium titanate (BST) has been deposited on-die to produce tuning capacitors. Previously, the high-k dielectric has always been too lossy to be of use, according to researchers at University ...

IRVINE, USA: WiSpry, Inc., the leader in high-performance tunable radio frequency (RF) semiconductor products for the wireless industry, today announced the WS1050 tunable RF capacitor, combining ...

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

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 ...

Designated the Stptic G2 range, the capacitors now have a 5:1 tuning ratio which means they can add extra correction when signal matching between a smartphone’s antenna and power amplifier. Other ...
