New crystal structure triples output power of GaN transistors, expands radar observation range

August 10, 2018 By Aimee Kalnoskas Leave a Comment

GaN transistors

Fujitsu and Fujitsu Laboratories have succeeded in developing a transistor that can provide both high current and high voltage in gallium-nitride (GaN) high electron mobility transistors (HEMT), effectively tripling the output power of transistors used for transmitters in the microwave band. Fujitsu’s crystal structure improves operating voltage by dispersing the applied voltage to the transistor, and […]
