Fujitsu and KDDI are coming out with a high-efficiency mobile WiMAX amplifier that could pave the way for cheaper and less energy consuming base stations. 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.
