PRODUCT DESCRIPTION
The AWT6224 addresses the demand for increased
integration in dual-band handsets for EGSM network
deployments. The small footprint 3 mm x 5 mm
x 1 mm surface mount RoHS compliant package
contains independent RF PA paths to ensure optimal
performance in both frequency bands, while achieving
a 25% PCB space savings compared with solutions
requiring two single-band PAs. The package pinout
was chosen to enable handset manufacturers
to easily route VCC to both power amplifiers and
simplify control with a common VMODE pin. The
device is manufactured on an advanced InGaP HBT
MMIC technology offering state-of-the-art reliability,
temperature stability, and ruggedness. The AWT6224
incorporates ANADIGICS’ HELP3™ technology to
provide low power consumption without the need for
an external voltage regulator. Two operating modes
provide optimum efficiency at high and medium/low
power output levels, thereby dramatically increasing
handset talk-time and standby-time. Its built-in voltage
regulator eliminates the need for external voltage
regulation and load switches. The 3 mm x 5 mm x 1
mm surface mount package incorporates matching
networks optimized for output power, efficiency and
linearity in a 50 Ω system.
