PRODUCT DESCRIPTION
The AWT6638 PA is designed to provide highly linear
output for WCDMA and LTE handsets and data
devices with high efficiency at both high and low power
modes. This HELP3DCTM PA can be used with an
external switch mode power supply (SMPS) to improve
its efficiency and reduce current consumption further
at medium and low output powers. A “daisy chainable”
directional coupler is integrated in the module thus
eliminating the need of external couplers. The
device is manufactured on an advanced InGaP HBT
MMIC technology offering state-of-the-art reliability,
temperature stability, and ruggedness. There are two
selectable bias modes that optimize efficiency for
different output power levels, and a shutdown mode
with low leakage current, which increases handset talk

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 VMODE1 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 VMODE1.
The Bias Control table lists the recommended modes
of operation for various applications. VMODE2 is not
necessary for this PA.
Two operating modes are available to optimize current
consumption. High Bias/High Power operating mode
is for POUT levels > 16 dBm. At around 17 dBm output
power, the PA can be “Mode Switched” to Low power
mode for lowest quiescent current consumption.

HELP3DCTM
The AWT6638 power amplifier module is based on
ANADIGICS proprietary HELP3DC™ technology. The PA is designed to operate up to 17 dBm in the low
power mode, thus eliminating the need for three gain
state, while still maintaining low quiescent current
and high efficiency in low and medium power levels. Average weighted efficiency can be increased by
using an external switch mode power supply (SMPS)
or DC/DC converter to reduce VCC.
The directional “daisy chainable” coupler is integrated
within the PA module, therefore there is no need for
external couplers.
The AWT6638 has an integrated voltage regulator,
which eliminates the need for an external constant
voltage source. The PA is turn on/off is controlled
by VEN pin. A single VMODE control logic (VMODE1) is
needed to operate this device. AWT6638 requires
only two calibration sweeps for system calibration,
thus saving calibration time.
Figure 11 shows one application example on mobile
board. C1 and C2 are RF bypass caps and should
be placed nearby pin 1 and pin 10. Bypass caps
C4 and C5 may not be needed. Also a “T” matching
topology is recommended at PA RFIN and RFOUT
ports to provide matching between input TX Filter and
Duplexer / Isolator.
