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 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 ...

Modern radios are often digital affairs, in which the frequency is derived from a stable crystal oscillator and varied through a microprocessor controlled frequency synthesiser. It won’t drift, and it ...

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 ...

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 ...

Peregrine Semiconductor’s DuNE technology solves one of the orneriest problems in RF design—antenna impedance matching. In every wireless application, an antenna has to be connected to the radio. That ...

Power system designers are constantly under pressure to attain larger power densities and improved conversion efficiencies, whether it is for data servers for the internet of things or data centers.
