PRODUCT DESCRIPTION
The AWT6321 addresses the demand for increased
integration in dual-band handsets for North American
CDMA network deployments. The small footprint 3
mm x 5 mm x 1 mm surface mount RoHS compliant
package contains independent RF PA paths to ensure
optimal performance in both frequency bands, while
achieving a 25% PCB space savings compared with
solutions requiring two single-band PAs. The package
pinout was chosen to enable handset manufacturers
to easily route VCC to both power amplifiers and
simplify control with a common V MODE pin. The
device is manufactured on an advanced InGaP HBT
MMIC technology offering state-of-the-art reliability,
temperature stability, and ruggedness. The AWT6321
is part of ANADIGICS’ High-Efficiency-at-Low-Power
(HELP™) family of CDMA power amplifiers, which
deliver low quiescent currents and significantly
greater efficiency without a costly external DAC or
DC-DC converter. Through selectable bias modes, the
AWT6321 achieves optimal efficiency across different
output power levels, specifically at low- and midrange power levels where the PA typically operates,
thereby dramatically increasing handset talk-time and
standby-time. Its built-in voltage regulator eliminates
the need for external switches. The 3 mm x 5 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 VENABLE and VMODE 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 VMODE
voltages. The Bias Control table lists the recommended
modes of operation for various applications.
