talk and standby time. A “daisy chainable” directional
coupler is 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.

PRODUCT DESCRIPTION
The AWT6625A HELP4^TM PA is the 4th generation
HELP^TM product for WCDMA devices operating in
UMTS800 (Band 5) and for CDMA devices operating
in Cell-band. This PA incorporates ANADIGICS’
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-
Plus^TM HBT technology offering state-of-the-art
reliability, temperature stability, and ruggedness.
Three selectable bias modes that optimize efficiency
for different output power levels and a shutdown
mode with low leakage current increase handset
