APPLICATIONS
PRODUCT DESCRIPTION
The AWT6274 meets the increasing demands for higher output power in UMTS handsets. The PA module is optimized for VREF = +2.85 V, a requirement for compatibility with the Qualcomm(R) 6275 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 mm x 4 mm x 1.1 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 system.

The device may be operated safely over these conditions; however, parametric performance is guaranteed only over the conditions defined in the electrical specifications.
Notes: (1) For operation at VCC = +3.2 V, POUT is derated by 0.5 dB. (2) For operation at 110 oC (TC), POUT is derated by 1.0 dB.

APPLICATION INFORMATION
To ensure proper performance, refer to all related Application Notes on the ANADIGICS web site: http://www.anadigics.com Shutdown Mode The power amplifier may be placed in a shutdown mode by applying logic low levels (see Operating Ranges table) to both the VREF and VMODE voltages. 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. Three operating modes are recommended to optimize current consumption. High Bias operating mode is for POUT levels > 16 dBm. At POUT <16dBm, the PA should be "Mode Switched" to Low Bias Mode. For POUT levels < ~7 dBm, the VCC can be switched to 1.5 V (Low Bias Mode is also used for this POUT range).
