PRODUCT DESCRIPTION
The AWT6138 PCS CDMA Power Amplifier is a high
performance CDMA2000/ 1XRTT amplifier designed
specifically for PCS wireless applications. This
rugged, easy to use InGaP HBT design delivers
state of the art efficiency and temperature stability
with very low DC power consumption. The
AWT6138 PA module has the lowest CDG currents
available to handset manufacturers today.
handset. The device has mode-switching to take
advantage of its high efficiency operation over a wide
range of output powers. Higher low power efficiency
is achieved without an external DAC or DC-DC
converter. The integrated power amplifier module
employs a proprietary bias control and temperature
compensation circuit that assures stable operation,
even at extreme temperature conditions.
A combination of low idle current and mode
switching enables the AWT6138 to deliver
unparalleled CDMA average power efficiencies.
This bias feature allows the AWT6138 to significantly
increase the battery usage time of a mobile
The self contained 4mm x 4mm surface mount
package incorporates matching networks optimized
for output power, efficiency and linearity in a 50[ohm]
system making it easy to incorporate the device into
BOTH new and existing designs.

APPLICATION INFORMATION
Bias Modes
The power amplifier may be placed in either a Low
Bias mode or a High Bias mode by applying the
appropriate logic levels (see Operating Ranges
table) to the VMODE Voltage. The Bias Control table
lists the recommended modes of operation for
various applications.
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 VREF and VMODE voltages.
