DURHAM, N.C. & CAMBRIDGE, Mass. -- February 20, 2013

Cree, Inc. (Nasdaq: CREE) and Eta Devices, Inc. will demonstrate the world’s
most efficient reported power amplifier for mobile base stations at the 2013
Mobile World Congress, February 24-28 in Barcelona, Spain.

Current generation mobile base station amplifiers employing silicon LDMOS
transistors can provide amplifier efficiencies up to 45 percent. By contrast,
Eta Devices’ next-generation power amplifiers are able to deliver efficiencies
higher than 70 percent under a 4G LTE modulation format, and are thus poised
to revolutionize current industry efficiency standards.

“Eta Devices’ next-generation power amplifiers leverage the performance and
reliability advantages of Cree’s GaN HEMT RF transistors to realize
game-changing efficiency benefits for the mobile base station industry,” said
Jim Milligan, business director, Cree RF. “Our transistors have been
instrumental in demonstrating Eta Devices’ amplifiers, which perform 50
percent more efficiently than the best incumbent silicon power amplifiers
currently available in the 4G LTE market.”

The world’s mobile networks consume approximately 120TWh of electricity per
year, and 50-80 percent of these networks’ power is consumed by their power
amplifiers and associated components. Implementing Eta Devices’ new power
amplifier solution on a global level could save mobile operators 60TWh of
energy per year, which is equivalent to the amount of power produced by more
than seven average-sized American nuclear power plants. It could also save up
to 50 percent of the $36.5 billion spent to power mobile base stations each

“Mobile operators gain dramatic advantages by adopting our new technology,”
said Mattias Astrom, CEO of Eta Devices. “In addition to cost savings, our
power amplifiers provide operators with a significantly reduced carbon
footprint, which contributes to a more sustainable planet. In fact, if
implemented on a global basis, our solution would reduce carbon emissions by
approximately 36 million tons per year, which is equivalent to eliminating the
annual greenhouse gas emissions produced by 7 million cars.”

Cree and Eta Devices’ demonstration of the new power amplifier will take place
at the Barcelona Mandarin Oriental on February 26 from 1:00 p.m. to 5:00 p.m.

About Eta Devices

Eta Devices’ disruptive technology solves the key power challenges in the
mobile communications industry.

In base stations, this leads to significantly reduced power consumption and
smaller cabinets. For handsets, battery life is considerably increased and
multiband communications can be enabled at a fraction of the cost and
footprint; this makes it possible to use the same handset model all over the

Eta Devices’ technology also contributes towards a sustainable world by
generating substantial carbon footprint reductions. Based on breakthrough
research from MIT, Eta Devices is a fabless semiconductor company
headquartered in Cambridge, MA with an R&D office in Stockholm, Sweden.
