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 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 Ω system.

PRODUCT DESCRIPTION
The AWT6635 PA is designed to provide highly linear
output for WCDMA ,CDMA and LTE 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
