use time. The AWT6751 is designed for use both
with and without average power tracking (APT). APT
can be used to optimize the VCC level for the desired
output power level and linearity, which greatly reduces
the total current drawn from the battery. This feature,
in conjunction with HPM and LPM operating modes,
enables significant improvements in overall power
added efficiency of the AWT6751 across the entire
dynamic range of operating powers. APT requires
use of an external variable voltage supply (DC-DC
converter), which is used to provide the variable
voltage to Vcc pad of the amplifier. In some cases, the
average current over the TS.09 power profile can be
reduced by more than 25%. A low-leakage shutdown
mode increases standby time.
The AWT6751 has built-in daisy-chainable RF
couplers for each band, which provide high directivity
and 20 dB coupling. The AWT6751 also incorporates
matching networks optimized for output power,
efficiency and linearity in a 50 Ω system. The device
is designed for use in systems where a single RF
input may be switched to drive band 1 and 8 antenna
outputs. AWT6751 is manufactured on an advanced
InGaP HBT MMIC technology offering state-of-the-art
reliability, temperature stability, and ruggedness.

PRODUCT DESCRIPTION
RFIN
AWT6751 addresses the demand for increased
integration in dual-band handsets for WCDMA and VEN_B1
CDMA/EVDO networks. The small footprint 3 mm VEN_B8
x 4 mm x 0.92 mm surface mount RoHS compliant VMODE
package contains independent RF PA paths to provide
optimized performance in each frequency band
in 1/3 less PCB area of two single-band PAs. The
AWT6751 is part of ANADIGICS’ ProEficient Plus™
family of power amplifiers, which deliver low quiescent
currents and excellent efficiency from fixed or variable
supply voltages. Two selectable bias modes optimize
efficiency for different ranges of output power levels
in average power tracking systems to improve device
