ANADIGICS' 3rd Generation Polar EDGE Power Amplifier Designed for Qualcomm Chipset Platforms

(Product News, 20 Feb 2008)

ANADIGICS Inc. has developed the AWT6155 quad-band polar EDGE power amplifier (PA) module designed to meet requirements for GSM and EDGE mode operation with Qualcomm's WCDMA and HSPA chipsets.

ANADIGICS' new 3rd generation quad-band polar EDGE PA delivers full power output in a 5x5mm package, half the size of current generation EDGE PA modules. The chip includes separate amplifier chains, one to support GSM850/900 bands, the other for DCS/PCS bands, which are both optimized for greater efficiency, power, and linearity in GMSK and 8PSK modulation. The PA includes an internal reference voltage and integrated power control scheme for simplified GMSK operation.

The AWT6155 incorporates ANADIGICS' proprietary InGaP-Plus technology for reliability, temperature stability and ruggedness. It is manufactured using a material set consistent with the European Union's Restriction of Hazardous Substances (RoHS).
