that optimize efficiency for different output power
levels, and a shutdown mode with low leakage current,
which increases handset talk and standby time. The
self-contained 3 mm x 3 mm x 1 mm surface mount
package incorporates matching networks optimized for
output power, efficiency, and linearity in a 50

PRODUCT DESCRIPTION
The AWT6631 PA is designed to provide highly linear
output for WCDMA, CDMA , LTE and TD-SCDMA
handsets and data devices with high efficiency at
both high and low power modes. This HELP3DC
TM
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
