PRODUCT DESCRIPTION
The AWT6388R is a high power, high efficiency
amplifier module for CDMA450 wireless applications.
The device is manufactured on an advanced InGaP
HBT MMIC technology offering state-of-the-art
reliability, temperature stability and ruggedness. A low
power quiescent current mode is digitally controlled to
reduce power drain on the system battery. The 4 mm
x 4 mm x 1 mm laminate package is self contained,
incorporating 50
Ω
input and output matching networks
optimized for output power, linearity, and efficiency.

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 both the V
REF
and V
MODE
voltages.
Bias Modes
The power amplifier may be placed in either a Low Bias
mode or a High Bias mode by applying the appropriate
logic level (see Operating Ranges table) to the V
MODE
