Caltech engineers build electronic chips that repair themselves

Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might ...

High-efficiency power amplifier could bring 5G cell phones

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 communications.

Power amplifiers for 5G made of gallium nitride

The wireless data transmission via mobile communication is reliable and affordable. However, data volume per user is rising exponentially. Causes are not only the continuously growing number of smartphones, but also trends ...

Ex-MIT company rethinks power-feasting amplifiers

(Phys.org)—Technologists generally agree that power amplifiers have proven to be inefficient pieces of hardware. Turning electricity into radio signals, they eat into the battery life of smartphones and they waste power. ...

World record silicon-based millimeter-wave power amplifiers

Two teams of DARPA performers have achieved world record power output levels using silicon-based technologies for millimeter-wave power amplifiers. RF power amplifiers are used in communications and sensor systems to boost ...

World's first GaN HEMT T/R module operating in the C-Ku band

Fujitsu Laboratories today announced that it has successfully developed the world's first transmitter/receiver (T/R) module using gallium-nitride (GaN)high electron mobility transistor (HEMT) technology that features an output ...
