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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
