WARREN, NJ — AWT6155 from Anadigics is a quad-band polar EDGE power amplifier (PA) module for 3G wireless handsets and equipment. Designed to meet requirements for GSM and EDGE mode operation with Qualcomm's WCDMA and HSPA chipsets, this 3rd generation quad-band polar EDGE PA delivers full power output in a smaller package. The 5 x 5mm package, half the size of current generation EDGE PA modules, 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.
Half the size of current generation 7 x 7-mm EDGE PA modules, the AWT6155 reduces RF board area in dual-, tri- and quad-band designs. It also has an internal reference voltage and integrated power control scheme for simplified GMSK operation, which makes production calibration faster and easier and reduces the number of external components required.
The AWT6155 incorporates the company's proprietary InGaP-Plus™ technology for state-of-the-art reliability, temperature stability and ruggedness. It is manufactured using a material set consistent with the European Union's Restriction of Hazardous Substances (RoHS).
In GMSK mode the PA offers integrated power control (CMOS), +35-dBm GSM850/900 output power, +33-dBm DCS/PCS output power, 55 percent GSM850/900 PAE, 52 percent DCS/PCS PAE and a power control range of over 50 dB.
In EDGE mode the AWT6155 offers +29-dBm GSM850/900 output power, +28.5-dBm DCS/PCS output power, 29 percent GSM850/900 PAE, 30 percent DCS/PCS PAE, 64-dB typical ACPR (400 kHz), and 74-dB typical ACPR (600 kHz).
