AWT6321 Datasheet | ANADIGICS

FEATURES APPLICATIONS - CDMA/EVDO & Cell & PCS Dual-band Wireless Handsets and Data Devices The AWT6321 addresses the demand for increased integration in dual-band handsets for North American CDMA network deployments. The small footprint 3 mm x 5 mm x 1 mm surface mount Ro HS pliant package contains independent RF PA paths to ensure optimal performance in both frequency bands, while achieving a 25% PCB space savings pared 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 mon V MODE pin. The device is manufactured on an advanced In Ga P HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. The AWT6321 is part of ANADIGICS’ High-Efficiency-at-Low-Power .. (HELP™) family of CDMA power amplifiers, which deliver low quiescent currents and significantly greater efficiency without a costly external DAC or DC-DC converter. Through selectable bias modes, the AWT6321 achieves optimal efficiency across different output power levels, specifically at low- and midrange power levels where the PA typically operates, thereby dramatically increasing handset talk-time and standby-time. Its built-in voltage regulator eliminates the need for external switches. The 3 mm x 5 mm x M28 Package 14 Pin 3 mm x 5 mm x 1 mm Surface Mount Module 1 mm surface mount package incorporates matching networks optimized for output power, efficiency and linearity in a 50 Ω system.
