APPLICATIONS
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
