Anadigics Inc. introduces its dual-band power amplifier (PA) module specially designed for 3G dual-band handsets used for EGSM network installations worldwide. Dubbed the AWT6224, this PA supports both IMT (UMTS2100) and EGSM (UMTS900) band operations.

Its design is crafted to meet WCDMA requirements and HSPA operation with Qualcomm's latest chipsets. It incorporates Anadigics' proprietary HELP3 technology, which reduces average current consumption by 75 per cent and provides up to 25 per cent increase in talk time in 3G handsets. The PA also includes a built-in voltage regulator and CMOS-compatible logic controls.

The AWT6224 also reduces current consumption without the use of an external DC-DC converter, thus reducing the number of external components required for an efficient design. Like the AWT6281, the AWT6224 incorporates ANADIGICS' proprietary InGaP-Plus technology for state-of-the-art reliability, temperature stability and ruggedness. The module is manufactured using a material set consistent with the RoHS.

Pricing is at Rs.123.79 ($3.07) each for 1,000 unit quantities. It is sampling now with volume production scheduled for the end of Q2 08.
