Philips’ researchers have micromachined electrically variable RF capacitors. The devices, which are the microscopic equivalent of air-spaced variable and switchable capacitors, can be integrated into ...

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 ...

Cavendish Kinetics recently announced the availability of production samples of its tunable RF capacitors to key strategic partners. Shipped as a chip scale package (CSP), the Cavendish digital ...

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 ...

The NCD2100 electronic programmable capacitance IC has a capacitance range of 6.6 to 37.55 pF in small 63-fF steps for shunt configuration. The digitally controlled capacitance trimming setting is ...

[Jezan] decided to introduce his son to electronics by building a small crystal radio. These crystal sets have been around for a long time, and make for a great beginner electronics project, but some ...

Although many High-Q capacitors are available on the market their performance can vary widely depending on design and the quality of manufacturing, as Scott Horton of Johanson Technology explains to ...

One of [Brian]’s hobbies is Amateur Ham radio, in which it is usually required to check that the transmitted signals are within specifications. As it isn’t safe to connect the radio’s output directly ...

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 ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...
