AWT6155

At this week's Mobile World Congress 2008, Anadigics Inc. has released the AWT6155 quad-band polar Edge power amplifier module for 3G wireless handsets and equipment.

Designed to meet requirements for GSM and Edge mode operation with Qualcomm's W-CDMA and HSPA chipsets, Anadigics' third-generation quad-band polar Edge power amplifier delivers full power output in a smaller package. The 5mm x 5mm package, half the size of current generation Edge power amplifier 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.

"The AWT6155 is half the size of current generation 7mm x 7mm Edge PA modules," said Joe DeMoura, Edge product line manager at Anadigics. "That reduces RF board area in dual-, tri- and quad-band designs based on the latest generation of Qualcomm transceivers. The smaller package includes features that our customers expect in a high-performance Edge power ampseparate amplifier chains for GSM850/900 and for DCS/PCS bands and optimized performance in both GMSK and 8PSK modes. The AWT6155 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 Anadigics' proprietary InGaP-Plus technology for high reliability, temperature stability and ruggedness. It is manufactured using a material set consistent with EU's RoHS.

Sampling of the AWT6155 amplifier will start by the end of Q1.
