EDGE Power Amp Module for 3G Phones, PDAs, and Wireless PC Cards
ANADIGICS, Inc. introduced 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 AWT6172 supports operation in the GSM850, GSM900, DCS, and PCS bands, and it delivers efficiencies of up to 55 percent in GMSK mode for longer talk-time, with a linearity of 64 dBc ACPR at 28.5 dBm output power level, making it especially attractive to handset makers. Featured in a small 6 x 6 x 1.1 mm package, the power amplifier module is built on InGaP-Plus HBT technology, and is EGPRS capable (class 12). Saturated output power in GMSK mode is rated at +35 dBm in the GSM850/900 bands, and at +33 dBm in the DCS/PCS bands.
