and linearity, which greatly reduces the total current
drawn from the battery. This feature, in conjunction
with selectable operating modes, enables significant
improvements in overall power added efficiency of
the AWC6325 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. A low-leakage shutdown mode increases
standby time. This PA has built-in directional couplers
for each band, with a common coupler output port
CPL_OUT. The 3 mm x 5 mm x 0.9 mm surface mount
package incorporates matching networks optimized
for output power, efficiency and linearity in a 50 Ω
system. The device is manufactured on an advanced
InGaP HBT MMIC technology offering state-of-the-art
reliability, temperature stability, and ruggedness.

AWC6325 addresses the demand for increased
integration in dual-band handsets for CDMA networks.
The small footprint 3 mm x 5 mm x 0.9 mm surface
mount RoHS compliant package contains independent
RF PA paths to ensure optimal performance in both
frequency bands in less board area than two single
band PAs. The package pinout was chosen to enable
handset manufacturers to independently provide
bias to both power amplifiers and simplify control
with common mode pins. The AWC6325 is part of
ANADIGICS’ 3rd generation of High-Efficiency-at-
Low-Power (HELP3E™) family of power amplifiers,
which deliver low quiescent currents and significantly
greater efficiency through selectable bias modes for
high, medium and low power operation. The AWC6325
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
