Anadigics’ 3G PAs power LG’s new ARENA handsets

Anadigics of Warren, NJ, USA says that its AWT6224, AWT6321 and AWT6222 3G dual-band power amplifier (PA) modules are being used in LG Electronics’ new ARENA (KM900) multimedia touch-screen handsets for the European, Asian and Central/South American markets.

The AWT6224 is a dual-band WCDMA/HSPA PA optimized for 3G connections in UMTS bands 1 and 8. The AWT6321 is a dual-band CDMA/EVDO PA designed for cell and PCS-band connections. The AWT6222 is a dual-band WCDMA/HSPA PA for 3G connections in UMTS bands 1 and 6.

With a 3-inch, 262K color touch-screen display, the LG KM900 ARENA offers provides tri-band GSM and 3G support, Wi-Fi, and GPS connectivity, as well as Bluetooth and USB. Running on a new user interface called S-class, the ARENA will be powered by a 1000mAh battery that is said to last for 300 hours of standby or 3 hours and 50 minutes of talk time. It also features mobile TV and a 5 megapixel built-in camera, which records DVD-quality videos.

“Anadigics has been a long-standing, strategic supplier of RF front-end solutions to LG Electronics,” says Dr Ali Khatibzadeh, Anadigics’ senior VP & general manager, RF Products. “We are proud to have been selected again as the vendor of choice for their new flagship touch-screen 3G smart phones.”

Anadigics says that its portfolio of 3G power amplifiers enables OEMs to rapidly deliver multiple versions of a new platform to different operators around the world. All three PA modules used in LG’s ARENA are available in identical 3mm x 5mm packages, reducing RF board area requirements and simplifying the layout.

All three devices have been developed using Anadigics’ HELP3 (high efficiency at low power) technology, which reduces average current consumption by 75% and provides up to 25% more talk time in 3G handsets. All three also use Anadigics’ proprietary InGaP-Plus technology for reliability, temperature stability and ruggedness.
