| AWT6251 PCS/WCDMA 3.4V/27.5 dBm Linear Power Amplifier Module PRELIMINARY DATA SHEET - Rev 1.1 FEATURES * * * * * * * InGaP HBT Technology High Efficiency: 38% Low Quiescent Current: 50 mA Low Leakage Current in Shutdown Mode: <1 A VREF = +2.85 V (+2.75 V min over temp) Optimized for a 50 System Low Profile Miniature Surface Mount Package: 1.56 mm Max AWT6251 APPLICATIONS * Dual Mode 3GPP Wireless Handsets M7 Package 10 Pin 4 x 4 x 1.5 mm Surface Mount Module PRODUCT DESCRIPTION The AWT6251 meets the increasing demands for higher output power in 3GPP handsets. The PA module is optimized for VREF = +2.85 V, a requirement for compatibility with the Qualcomm(R) 6250 chipset. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. Selectable bias modes that optimize efficiency for different output power levels, and a shutdown mode with low leakage current, increase handset talk and standby time. The self-contained 4 x 4 x 1.5 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 system.

Bias Modes The power amplifier may be placed in either a Low Bias mode or a High Bias mode by applying the appropriate logic level (see Operating Ranges table) to the VMODE voltage. The Bias Control table lists the recommended modes of operation for various applications.
