PRODUCT DESCRIPTION
The AWT6628A HELP4^TM PA is a 4th generation
HELP^TM product for WCDMA devices operating in
UMTS900 (Band 8) . This PA incorporates ANADIGICS’
RFIN
2
HELP4^TM technology to deliver exceptional efficiency
at low power levels and low quiescent current without
the need for external voltage regulators or converters.
The device is manufactured using advanced InGaP-
VMODE2
3
Plus^TM HBT technology offering state-of-the-art
reliability, temperature stability, and ruggedness.
Three selectable bias modes that optimize efficiency VMODE1 ⁴
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
integrated in the module, thus eliminating the need of
VEN ⁵
an external coupler. The self-contained3 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.
