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 1.5 mm surface mount
package incorporates matching networks optimized
for output power, efficiency, and linearity in a 50 Ω
system.

•InGaP HBT Technology
•High Efficiency: 38%
•Low Quiescent Current: 50 mA
•Low Leakage Current in Shutdown Mode: <1 µA
•VREF = +2.85 V (+2.75 V min over temp)
•Optimized for a 50 Ω System
•Low Profile Miniature Surface Mount Package:
1.56 mm Max
•RoHS Compliant Package Option, 250 oC MSL-3

•Dual Mode 3GPP Wireless Handsets
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® 6250 chipset. The
device is manufactured on an advanced InGaP HBT
MMIC technology offering state-of-the-art reliability,
temperature stability, and ruggedness. Selectable

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent
damage. Functional operation is not implied under these conditions.
Exposure to absolute ratings for extended periods of time may
adversely affect reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric performance is guaranteed
only over the conditions defined in the electrical specifications.

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.
Table 5: Bias Control
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.
