PRODUCT DESCRIPTION
The AWT6278 HELP3^TM PA is the 3rd generation
WCDMA product for UMTS handsets. This PA
incorporates ANADIGICS’ HELP3^TM technology to
provide low power consumption without the need for an
external voltage regulator. The device is manufactured
on an advanced InGaP HBT MMIC technology offering
state-of-the-art reliability, temperature stability, and
ruggedness. There are three selectable bias modes
that optimize efficiency for different output power
levels, and a shutdown mode with low leakage
