Maker of wireless and broadband communications components and modules, Anadigics Inc of Warren, NJ, USA has introduced its AWE6174 quad-band polar EDGE PA module for 3G wireless handsets and equipment. The launch took place at this week’s 2008 GSMA Mobile World Congress 2008 event in Barcelona, Spain.

Based on Anadigics’ proprietary InGaP-Plus technology, the AWE6174 is designed to meet all requirements for GSM/GPRS and EDGE operations in dual-, tri- or quad-band handsets based on Qualcomm’s WCDMA, HSPA chipsets and their latest generation transceivers. It includes separate amplifiers for GSM850/900 and for DCS/PCS bands, which are optimized for performance in both GMSK and 8PSK modes. According to Anadigics, the AWE6174’s 6 x 6mm package is 25% 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, says the company.

"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," says EDGE product line manager Joe DeMoura. "Using a 3rd 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."

Sampling of the AWE6174 is expected to begin at the end of Q1/2008.
