GREENSBORO, NORTH CAROLINA - MAY 21, 2007 - 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 quad-band linear EDGE power amplifier (PA) module is supporting Samsung's E250 EDGE handset. The Samsung E250 provides consumers state-of-the-art performance and advanced multimedia functionality in a sleek, compact design. The highly stylish E250 slider phone features a VGA camera, an MP3 player, advanced audio distribution profile (A2DP) stereo Bluetooth® capability and a vivid 2.0" color screen. The Samsung E250 is currently among Samsung's best selling handsets. "We are very pleased that Samsung has selected the RF3159 to power the highly popular and stylish E250 handset," said Konrad Alvarino, general manager, components business unit at RFMD. "Top tier handset manufacturers such as Samsung continue to select our linear EDGE power amplifiers as a result of their superior efficiency and linearity performance. We look forward to supporting Samsung with our industry-leading EDGE power amplifiers in future EDGE and 3G multimode handsets." 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 NXP Semiconductors and Infineon Technologies. Designed to be the final amplification stage in a dual-mode GSM/GPRS/EDGE mobile transmit lineup, the product's gain and linearity lineups enable handset manufacturers to optimize the transmit chain to meet varying implementations of linearity, efficiency and output power. Fully quad-band capable, the RF3159 operates in the 824MHz to 915MHz and 1710MHz to 1910MHz bands. RFMD is the leading supplier of linear EDGE and large signal polar modulation (LSPM) EDGE power amplifiers. The Company anticipates additional tier-one EDGE handsets will feature its linear EDGE PA modules this year. Additionally, the Company recently sampled two new EDGE front end products - the RF3161 LSPM EDGE PA module and the RF3203 linear EDGE transmit module (TxM) - and RFMD anticipates continued favorable design activity related to its industry-leading EDGE product portfolio.
