After optimizing the amplifier circuits of a gallium-nitride (GaN) HEMT device, Fujistu went on to build a prototype transmitter amplifier that can attain power efficiency of about 30 percent with 25W power output in the 2.5GHz operational spectrum. This level is twice the efficiency of existing amplifiers.
