Anadigics launches dual-band HELP3 PA for EGSM

Anadigics Inc of Warren, NJ, USA has launched the AWT6224 dual-band HELP3 power amplifier (PA) module, which is designed specifically for use in 3G dual-band handsets for EGSM network deployments worldwide (especially Europe).

The latest member of Anadigics’ rapidly growing family of WCDMA power amplifiers, the AWT6224 PA is a dual-band module that supports both IMT (UMTS2100) and EGSM (UMTS900) band operations, and is designed to meet requirements for WCDMA and HSPA operation with Qualcomm’s latest chipsets. The power amplifier incorporates Anadigics’ proprietary HELP3 technology without the use of an external DC-DC converter, reducing the number of external components required for an efficient design. This reduces average current consumption by 75% and provides up to 25% increased talk time in 3G handsets, the firm claims. It also includes a built-in voltage regulator and CMOS-compatible logic controls.

“Our new AWT6224 PA delivers the 3G HSPA performance required by two European bands in a single 3mm x 5mm package,” explains Ali Khatibzadeh, senior VP and general manager of Wireless Products. “Its smaller size reduces the RF board area required for multi-band phone designs utilizing Qualcomm’s latest generation chip-sets.”

Like the AWT6281 linear PA launched last week for EGSM, the AWT6224 incorporates Anadigics’ proprietary InGaP-Plus technology for reliability, temperature stability and ruggedness.

Priced at $3.07 each in 1000-unit quantities, the AWT6224 is sampling now, with volume production scheduled for the end of Q2/2008.
