Gallium nitride: half the space, double the power

Innovation in silicon power supplies helped cut these old models down to a more manageable size, but those improvements have been mined to the limit. Silicon simply can't run at the frequencies necessary to deliver more power without growing in size. That's a critical factor for 5G wireless network rollout, for the future of robotics and for technology from renewable energy to data centres.

"Engineers have reached the limit – they can't push more power in the space they have and they don't want to increase the space their equipment needs," said Masoud Beheshti, a product manager at our company. "If the form factor can't change, the only knob you can play with is power density."
