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
AWT6388
To ensure proper performance, refer to all related
Application Notes on the ANADIGICS web site:

Shutdown Mode
The power amplifier may be placed in a shutdown
mode by applying logic low levels (see Operating
Ranges table) to both the VREF and VMODE voltages.
voltage. The Bias Control table lists the recommended
modes of operation for various applications.
High Bias Mode is recommended for POUT levels >
16 dBm. At POUT <16dBm. The PA should be “Mode
Switched” to Low Bias Mode to improve efficiency and
reduce current consumption at power output levels
below 16 dBm.
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 VMODE
