Flagship Phones Leveraging Skyworks’ Front-End Solutions

WOBURN, Mass.--(BUSINESS WIRE)--Oct. 12, 2009-- Skyworks Solutions, Inc. (NASDAQ:SWKS), an innovator of high reliability analog and mixed signal semiconductors enabling a broad range of end markets, today announced that it is powering several of LG Electronics’ newest multimedia handsets. In particular, Skyworks’ front-end solutions are at the heart of LG’s GM200, GR500 and KP500 -- innovative platforms with enhanced touchscreen, audio, camera and messaging functionality.

“Skyworks is pleased to support LG with our family of high-quality 3G and 4G front-end solutions, particularly as they launch their suite of next generation, feature-rich mobile handsets,” said Liam K. Griffin, senior vice president, sales and marketing for Skyworks. “As a valued business partner, we look forward to further enhancing our relationship with LG as they increasingly expand their global mobile communications presence.”

About LG’s Newest Handsets
The LG-GM200 camera mobile phone has a 2.1 channel active sub-woofer with dual-side speakers, Dolby mobile, wireless FM radio with recording smart profiling, a 2 megapixel (MP) camera with video recording, Bluetooth® 2.0, MicroSD memory port, radio alarm, and up to 10 hours of talk time.

The innovative LG-GR500, or Xenon, features a large touch screen with vibration feedback and enhanced flash equating to increased functionality, full slideout 4-line QWERTY keyboard, music player, speaker independent voice commands, enhanced user interface, MicroSD memory port, 2 MP camera and camcorder with flash, is Bluetooth® capable, and offers advanced messaging.

The attractively-priced LG-KP500 utilizes a high-end full 3 inch touch screen phone with improved navigation to watch videos, play motion-sensor games, and look at photos. In addition, the handset contains an active flash user interface (UI), handwriting and editing functionality, auto-rotating display, and an embedded stylus pen.

About Skyworks’ Front-End Solutions
The small and efficient SKY77175 dual-band power amplifier (PA) for WCDMA/HSDPA band II (1850-1910 MHz), band V (824-849 MHz) is a fully matched, 14-pad surface-mount technology (SMT) module that meets the stringent spectral linearity requirements of WCDMA transmission, high power-added efficiency (PAE) for power output to 29 dBm (Band II) and 29 dDm (Band V), and a low current analog pad (VCONT) to improve efficiency for the low RF power range operation.

The SKY77340 PA module is designed in a compact-form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, PCS1900, supporting gaussian minimum shift keying (GMSK) and linear EDGE modulation, and Class 12 GPRS multi-slot operation. Two separate HBT PA blocks supporting the GSM850/900 band and the DCS1800/PCS1900 band are fabricated onto indium gallium arsenide (InGaP) die. Inputs and outputs are impedance-matched to 50 ohms, and a custom complementary metal oxide semiconductor (CMOS) IC provides the internal MFC function and interface circuitry.

The SKY77521 transmit and receive (Tx-Rx) front-end module (FEM), designed in a very low profile (1 mm), contains compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800 and PCS1900 operation – making it a complete transmit VCO-to-antenna and antenna-to-receive surface-acoustic wave (SAW) filter solution. The FEM also supports Class 12 GPRS multi-slot operation and EDGE polar modulation. WCDMA switch-through support is provided by three dedicated high-linearity ports.

The SKY77531 Tx/Rx integrated phase and amplitude controller (iPAC) FEM is in a low profile compact form factor, and supports quad-band cellular handsets operating GSM850/900 and DCS1800/PCS1900, and Class 12 GPRS multi-slot operation. The module consists of separate GSM850/900 and DCS1800/PCS1900 PA blocks, 50-ohm impedance-matched inputs and outputs, TX harmonics filtering, high linearity and a low insertion loss pseudomorphic high electron mobility transistor (pHEMT) RF switch, and a PAC block with internal current sense resistor.
