DURHAM, N.C., -- Cree, Inc. (Nasdaq: CREE - News) announced today that
it will demonstrate three new gallium nitride (GaN) high electron
mobility transistors (HEMT) targeted for WiMAX applications ranging
from 2.4 to 3.9 GHz next week. The new power transistors are debuting
at Booth 1143 at the IEEE MTT-S International Microwave Symposium 2006
in San Francisco, June 13-15.
Cree's new 30- and 120-watt transistors (CGH35030 and CGH35120)
augment the 15-watt CGH35015 released for sample shipments last month.
Together, these devices cover multiple WiMAX applications requiring
from 2 to 12 watts average orthogonal frequency division multiplexing
(OFDM) output power in the 3.3 to 3.9 GHz frequency band. Cree will
also demonstrate the new 15-watt CGH27015, the first in a new line of
Cree transistors targeted to address the 2.4 to 2.9 GHz North American
"We are pleased to be showcasing our new WiMAX transistors at this
year's MTT show. When fully released later this year, the CGH35030,
CGH35120, and CGH27015 will add to our growing line of standard wide
bandgap (WBG) WiMAX products and are expected to provide great
versatility to WiMAX base transceiver station (BTS) and consumer
premise equipment (CPE) designers," said Jim Milligan, Cree's product
manager for wide bandgap radio frequency products.
In addition, Cree's manager of RF product development, Simon Wood,
will present a paper entitled "High Efficiency, High Linearity GaN
HEMT Amplifiers for WiMAX Applications" at the MTT-S International
Microwave Symposium Workshop on "Advances in GaN HEMT Device
Technology, Modeling and Applications" June 11.

WiMAX is a standards-based wireless technology that provides
high-throughput connections over long distances. It can be used for
multiple applications, including last-mile broadband access, hotspots,
cellular backhaul, high-speed enterprise connectivity, and
non-line-of-sight mobile connectivity.
About Cree, Inc.
Cree is a market-leading innovator and manufacturer of semiconductors
and devices that enhance the value of solid-state lighting, power and
communications products by significantly increasing their energy
performance and efficiency. Key to Cree's market advantage is its
world-class materials expertise in silicon carbide (SiC) and gallium
nitride (GaN) for chips and packaged devices that can handle more
power in a smaller space while producing less heat than other
available technologies, materials and products.
Cree drives its increased performance technology into multiple
applications including exciting alternatives in brighter and more
tunable light for general illumination, backlighting for more vivid
displays, optimized power management for high-current switch-mode
power supplies and variable speed motors, and more effective wireless
infrastructure for data and voice communications. Cree customers range
from innovative lighting-fixture makers to defense-related federal
Cree's product families include blue and green LED chips, lighting
LEDs, LED backlighting solutions, power-switching devices and
radio-frequency/wireless devices. For additional product

This press release contains forward-looking statements involving risks
and uncertainties, both known and unknown, that may cause actual
results to differ materially from those indicated. Actual results may
differ materially due to a number of factors, such as the risk we may
encounter delays or other difficulties in ramping up production of our
new products and achieving commercial release; the risk we may be
unable to manufacture products with sufficiently low cost to offer
them at competitive prices or with acceptable margins; the rapid
development of new technology and competing products that may impair
demand or render our products obsolete; the potential lack of customer
acceptance for the products; variations in demand for Cree's products
and its customers' products; and other factors discussed in Cree's
filings with the Securities and Exchange Commission, including its
