PRODUCT DESCRIPTION
GND at Slug (pad)
The AWT6628A HELP4TM PA is a 4th generation
HELPTM product for WCDMA devices operating in
UMTS900 (Band 8) . This PA incorporates ANADIGICS’
HELP4TM 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 InGaPPlus 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 talk and
standby time. A “daisy chainable” directional coupler is
integrated in the module, thus eliminating the need of

APPLICATION INFORMATION
To ensure proper performance, refer to all related
Application Notes on the ANADIGICS web site:
http://www.anadigics.com
to the VMODE voltages. The Bias Control table below
lists the recommended modes of operation for various
applications.
Shutdown Mode
The power amplifier may be placed in a shutdown mode
by applying logic low levels (see Operating Ranges
table) to the VEN, VMODE1 and VMODE2 voltages.
Three operating modes are recommended to optimize
current consumption. High Bias/High Power operating
mode is for POUT levels > 17 dBm. At ~17dBm - 7
dBm, the PA should be “Mode Switched” to Medium
Power Mode. For POUT levels < ~7 dBm, the PA can be
switched to Low Power Mode for even lower quiescent
current consumption.
Bias Modes
The power amplifier may be placed in either Low,
Medium or High Bias modes by applying the
appropriate logic level (see Operating Ranges table)
