Anadigics, Inc.’s AWT6281 is the newest member of its HELP3 WCDMA linear power amplifier (PA) family. It is engineered specifically for use in advanced 3G handsets for EGSM (Band 8) UMTS wireless networks. This new third generation PA 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, said Anadigics.

The AWT6281 provides full compliance with HSDPA and HSUPA requirements and reduces average current consumption by 75% compared to competing devices, according to Anadigics. The PA provides exceptionally low quiescent currents of 7 mA without a DC-DC converter and eliminates the need for an external voltage regulator. Offering 880 – 915 MHz frequency range, the self-contained 4 mm x 4 mm x 1.1 mm surface mount package incorporates matching networks optimized for output power, efficiency and linearity in a 50 Ohm system, said the manufacturer. The PA’s efficiency is given as 42% at Pout of 29 dBm and 21% at Pout of 16 dBm, respectively. The AWT6281 is based on the company’s patented InGaP-Plus technology, which combines bipolar and FET devices on the same GaAs die.
