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
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.

COMMENTS
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 and TC = +90 OC, POUT is derated by 0.5 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.
