AWT6221

The AWT6221R addresses the demand for increased integration in dual-band handsets for Cingular's North American WCDMA network deployments. The small footprint 3 mm x 5 mm x 1 mm surface mount RoHS compliant package contains independent RF PA paths to ensure optimal performance in both frequency bands, while achieving a 25 % PCB space savings compared with solutions requiring two single-band PAs. The package pinout was chosen to enable handset manufacturers to easily route VCC to both power amplifiers and simplify control with a common VMODE pin. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness.

The AWT6221R incorporates ANADIGICS' HELP3? technology to provide low power consumption without the need for an external voltage regulator. Two operating modes provide optimum efficiency at high and medium/low power output levels, thereby dramatically increasing handset talk-time and standby-time. Its built-in voltage regulator eliminates the need for external voltage regulation and load switches. The 3 mm x 5 mm 1 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 system...
