The AWC6344 is a HELP
TM
product for CDMA
devices operating in AWS/KPCS band. This PA
incorporates ANADIGICS’ HELP
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 HBT technology
offering state-of-the-art reliability, temperature stability,
and ruggedness. Two 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 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.

APPLICATION INFORMATION
To ensure proper performance, refer to all related
Application Notes on the ANADIGICS web site:
http://www.anadigics.com
Shutdown Mode
The power amplifier may be placed in a shutdown
mode by applying logic low levels (see Operating
Ranges table) to the V
EN
and V
MODE
voltages.
Bias Modes
The power amplifier may be placed in either Low or
High Bias modes by applying the appropriate logic
level (see Operating Ranges table) to the V
MODE
pin.
The Bias Control table below lists the recommended
modes of operation for various applications.
Two operating modes are recommended to optimize
current consumption. High Bias/High Power operating
mode is for P
OUT
levels
>
16 dBm. At about 16 dBm,
the PA could be switched to Low Power Mode.
