Quad-band Power Amplifier Module
ANADIGICS, Inc. introduces a quad-band Linear EDGE (Enhanced Data rate for GSM Evolution) power amplifier module for 2.75G and 3G cell phones, PDAs and wireless PC cards that use the globally-accepted GSM/EDGE cellular standard. The EDGE standard has been adopted by most GSM operators worldwide either in combination with UMTS WCMDA (3G) or as a stand-alone upgrade (2.75G) to the GSM/GRPS (2.5G) system. There are two predominant hardware architectures adopted by baseband chipset suppliers serving the EDGE market Polar and Linear. The AWT6172 is a quad-band GPRS/EDGE power amplifier module designed for the linear EDGE architecture adopted by several base-band chipset suppliers. ANADIGICS has also announced products for the Polar EDGE architecture adopted by top-tier 3G chipset suppliers.
