GaN HEMTs minimize cellular network energy needs.
Press Release Summary:
November 12, 2012 - Operating at 100 or 200 W output powers, 50 V GaN HEMT Devices are available for both 1.8–2.2 GHz and 2.5–2.7 GHz frequency bands. Units are internally matched for optimum performance, enabling wide instantaneous bandwidths. Transistors are suitable for use in high efficiency Doherty power amplifiers where power gains higher than 18 dB at 2.14 GHz and 16 dB at 2.6 GHz can be achieved.

Cree Releases New Generation 50V GaN HEMT Technology to Significantly Reduce Cellular Network Energy Needs
Press release date: October 29, 2012
While operational cost savings from increased efficiency can be significant, additional substantial savings are also possible in the acquisition cost of the system. A higher efficiency power amplifier can help OEMs save capital equipment costs through simplified cooling, and the higher voltage GaN components can lower the cost of AC-to-DC and DC-to-DC converters. Overall, the impact on the total bill of materials can be as much as 10 percent, leading to significantly lower system costs.
“We believe our 50V GaN HEMT products can have a large impact in not only helping cellular network operators and OEMs reduce operational and capital expenses but also in helping to reduce global energy consumption,” explains Jim Milligan, business director, Cree RF. “Several tier one telecom OEMs have already incorporated lower voltage versions of our technology to begin realizing these benefits. To date, even at an early stage of deployment, we estimate as much as 2,400 MWh of energy has already been saved as a result. This is an equivalent carbon offset of 1,400 metric tons of CO2 and represents the offset created by planting approximately 36,000 trees."
Cree’s 50V GaN HEMT transistors operating at 100W or 200W output powers are now released for both the 1.8 - 2.2 GHz and 2.5 - 2.7 GHz frequency bands. The devices are internally matched for optimum performance, enabling wide instantaneous bandwidths. Cree 50V GaN HEMT transistors are ideal for use in high efficiency Doherty power amplifiers where power gains higher than 18dB at 2.14 GHz and 16 dB at 2.6 GHz can be achieved respectively.
