Anadigics Inc. has announced its new AWE6174 quad-band Polar Edge power amplifier (PA) module for 3G wireless handsets and equipment.

The company's new Polar Edge PA is designed to meet all requirements for GSM/GPRS and Edge operations in dual-, tri- or quad-band handsets based on Qualcomm's W-CDMA, HSPA chipsets and their latest-generation transceivers. The AWE6174 PA includes separate amplifiers for GSM850/900 and for DCS/PCS bands, which are optimized for high performance in both GMSK and 8PSK modes in a 6mm x 6mm package that is 25 percent smaller than current-generation EDGE PA modules. An internal reference voltage and integrated power control scheme for simplified GMSK operation make production calibration faster and easier and reduce the number of external components required.

"The unique device architecture in our new AWE6174 Polar EDGE PA gives handset designers the option of using an external DC/DC converter to modulate the amplifier bias voltage and reduce current consumption at backed off output power," said Joe DeMoura, Anadigics Edge product line manager. "Using a third-party DC/DC converter in this way can reduce current consumption by half at medium output power and greatly increase battery life and talk time."

The AWE6174 incorporates the company's proprietary InGaP-Plus technology for reliability, temperature stability and ruggedness. The PA is manufactured using a material set consistent with RoHS.

Product sampling of the AWE6174 amplifier is scheduled for the end of Q1 2008.

Anadigics will be one of the exhibitors at IIC-China 2008.
