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 ...

The need for what’s called antenna tuning—either by adjusting the antenna itself or via a matching circuit between power-amplifier output and the antenna—is almost as old as wireless itself. Even in ...

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 ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

IRVINE, Calif.--(BUSINESS WIRE)--WiSpry, Inc., the leader in high-performance tunable radio frequency (RF) semiconductor products for the wireless industry, today announced the WS1040 tunable RF quad ...

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 ...

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 ...

Simplified continuous tuning of filters, impedance matching networks, and antennas has become a crucial design element in modern mobile devices. Wireless 3G/4G technologies, Wi-Fi, Bluetooth, GPS, and ...
