Description:

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 Ω system.
