NEC Corporation has developed a power amplifier that will serve as a key device for mobile access and fronthaul/backhaul wireless communication equipment to enable high-speed, high-capacity communications for 5G Advanced and 6G networks. This power amplifier uses GaAs technology that can be mass-produced and has achieved the world’s highest output power of 10 mW in the 150 GHz band. Capitalizing on this, NEC aims to fast-track both equipment development and social implementation.
