RFMD(R) Edge Power Amplifier Supports World's Thinnest Slider Phone.

SGH-D900 Is Part of Samsung's Ultra Edition Line Of Handsets

GREENSBORO, N.C. -- RF Micro Devices, Inc. (NASDAQ: RFMD), a global leader in the design and manufacture of high-performance radio systems and solutions for applications that drive mobile communications, today announced that its RF3159 linear EDGE power amplifier (PA) is supporting Samsung's SGH-D900 "Black Carbon" mobile phone, the thinnest slider phone in the world. A member of Samsung's Ultra Edition line of handsets, the SGH-D900 is a GSM/GPRS/EDGE quad-band handset featuring an MP3 player with a micro SD-card expansion slot, 3.13 megapixel camera, support for a Bluetooth[R] stereo headset, TV-output and a vivid 2.1" 262K color screen for a full multimedia experience. Samsung's use of the RF3159 further extends RFMD's industry leadership in EDGE PAs and supports the Company's continued growth in the EDGE market.

"RFMD's RF3159 provides Samsung with a highly integrated, value-added RF solution, which will enable Samsung to further develop ultra slim mobile phones in various form factors, as well as strengthen its growing portfolio," said RFMD President and CEO Bob Bruggeworth. "The ongoing relationship between Samsung and RFMD will continue to grow as our Company works to provide superior EDGE product offerings."

"RFMD and Samsung collaborated to define this high performance EDGE PA," said RFMD General Manager of Components Business Unit Konrad Alvarino. "There are no other linear EDGE PAs on the market today that have this level of efficiency and linearity performance."

The RF3159 is a high linearity quad-band GSM/GPRS/EDGE PA designed to support EDGE transceivers utilizing a linear transmit architecture, including transceivers by Silicon Laboratories, Infineon Technologies and NXP Semiconductors. The RF3159 PA module is fully matched for easy implementation and is housed in a small 6x6mm package, which is industry-leading for the linear EDGE PA market. The product's gain and linearity lineups enable handset manufacturers to optimize the transmit chain to meet various requirements of linearity, efficiency and output power. The module is designed to be the final amplification stage in a dual-mode GSM/GPRS/EDGE mobile transmit lineup operating in the 824MHz to 915MHz and 1710MHz to 1910MHz bands.

The RF3159 demonstrates RFMD's continued success as the leading supplier of EDGE PAs and is also the leading supplier of merchant market EDGE transceivers. RFMD anticipates continued sales growth in the EDGE handset market, which the Company forecasts will grow by greater than 50% in 2007.
