The AWT6628A HELP4
TM
PA is a 4th generation
HELP
TM
product for WCDMA devices operating in
UMTS900 (Band 8) . This PA incorporates ANADIGICS’
RF

HELP4
TM
technology to deliver exceptional efficiency
at low power levels and low quiescent current without
the need for external voltage regulators or converters.

MODE2
The device is manufactured using advanced InGaP-
Plus
TM
HBT technology offering state-of-the-art
reliability, temperature stability, and ruggedness.
Three selectable bias modes that optimize efficiency
V
MODE1
for different output power levels and a shutdown mode
with low leakage current increase handset talk and
standby time. A “daisy chainable” directional coupler is

EN
integrated in the module, thus eliminating the need of
an external coupler. The self-contained 3 mm x 3 mm
x 1 mm surface mount package incorporates matching
networks optimized for output power, efficiency, and
linearity in a 50
Ω system.
