This diagram shows the standard layout of transistors in cell phone power amplifiers, at left, and a new highly efficient amplifier design, at right. The new design could help make possible ...

In what may be the most impractical discovery I’ve ever made, it came to my attention last week that sea caves make serviceable cell phone amplifiers. Last weekend I was on an 88-foot liveaboard dive ...

After experiencing a long inventory adjustment period, Taiwan-based Win Semiconductors, Visual Photonics Epitaxy Company (VPEC), and Advanced Wireless Semiconductor Company (AWSC) have started to see ...

A new highly efficient power amplifier for electronics could help make possible next-generation cell phones, low-cost collision-avoidance radar for cars and lightweight microsatellites for ...
