The AWT6281 extends the operating time of 3G handsets and data cards, which is critical for successful operation using today's high speed packet access (HSPA) networks.

Anadigics has released the AWT6281 Help3 WCDMA linear power amplifier (PA) engineered specifically for use in advanced 3G handsets for EGSM (Band 8) UMTS wireless networks.

The new power amplifier extends the operating time of 3G handsets and data cards, which is critical for successful operation using today's high speed packet access (HSPA) networks.

The AWT6281 is he latest member of Anadigics' family of 3G Help3 WCDMA linear power amplifiers.

It provides full compliance with HSDPA and HSUPA requirements and reduces average current consumption by 75% compared to competing devices.

The PA provides quiescent currents of 7mA without a DC/DC convertor and eliminates the need for an external voltage regulator.

The self-contained 4 x 4 x 1.1mm surface mount package incorporates matching networks optimised for output power, efficiency and linearity.

The AWT6281's superior performance and integration capabilities are achieved using Anadigics' InGaP-Plus technology which combines bipolar and FET devices on the same GaAs die.

Engineered for UMTS900 operation, Anadigics' new AWT6281 PA enables manufacturers to design and develop the advanced 3G handsets and data cards required for successful conversion to UMTS900 worldwide.
