WCDMA Power Amplifier integrates dual-band functionality.February 21, 2007 -
Incorporating ANADIGICS HELP3(TM) technology, AWT6221 combines North American cellular and PCS bands in 3 x 5 mm package. Intelligent bias circuit with selectable bias modes reduces current consumption to 8 mA, and built in voltage regulator functionality eliminates need for external switch circuitry. Designed for US 3G handsets and world-phones, solution is built upon InGaP-Plus(TM) technology, which integrates bipolar and FET devices on same InGaP GaAs die.

ANADIGICS Extends HELP3(TM) Family with Dual-Band WCDMA PA
BARCELONA, Spain, Feb. 13 -- ANADIGICS, Inc. (NASDAQ:ANAD), a leading supplier of wireless and broadband solutions, announces at 3GSM Congress in Barcelona Spain that it has expanded its successful line of HELP3(TM) WCDMA power amplifiers (PAs) with a new dual-band design. The AWT6221 combines North American cellular and PCS bands in a single 3 x 5mm package incorporating field-proven efficiency advantages of ANADIGICS HELP3(TM) technology. The AWT6221 is designed for both US 3G handsets and world-phones. Through the integration of two independent PA chains, the tiny AWT6221 delivers uncompromised performance in both frequency bands and conserves printed-circuit board area.
Leveraging ANADIGICS' proprietary HELP3(TM) technology, the AWT6221 dramatically reduces average current consumption by 75%, which translates to up to 25% increase in talk-time. ANADIGICS' HELP3(TM) PAs like AWT6221 use the Company's exclusive InGaP-Plus(TM) technology, which integrates bipolar and field-effect transistor (FET) devices on the same InGaP GaAs die. Through selectable bias modes, the HELP3(TM) PAs achieve optimal efficiency across the low-range and mid-range output power levels. The intelligent bias circuit of AWT6221 reduces current consumption to 8mA at low power levels -- the world's best.
"ANADIGICS has leveraged its extensive RF technology and design differentiation to deliver multi-band 3G HSPA power amplifiers with best-in- class performance and size," said Dr. Ali Khatibzadeh, Senior Vice President and General Manager of Wireless Products at ANADIGICS. "The AWT6221 sets a new industry benchmark in performance and size for WCDMA power amplifiers and extends ANADIGICS leadership in 3G RF PA market."
The AWT6221 dual-band PA from ANADIGICS offers superior integration by combining North American cellular and PCS bands in a small 3 x 5 mm package. As a result, using the HSDPA compliant device saves 53% PCB space when compared with implementations using two single-band 4 x 4 mm PAs. The chip includes built in voltage regulator functionality, which eliminates the need for external switch circuitry.
