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 ...

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 ...

Jamming LTE base stations easier than you may think

(Phys.org)—This much everyone knows: As technologies break new ground in speed and performance, mischief-makers also break new ground in finding ways to disrupt. Now an academic research group has warned a U.S. government ...

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. ...

NXP brings GaN technology mainstream

At IMS2011 this week, NXP Semiconductors N.V. is showcasing a live demo of its next-generation products based on Gallium Nitride (GaN) technology.

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 ...
