PRODUCT DESCRIPTION
The AWT6622 HELP4^TM PA is a 4th generation
HELP^TM product for UMTS1900 (Band 2) devices
and for CDMA/EVDO devices operating in the PCS
band. This PA incorporates ANADIGICS’ HELP4^TM
technology to deliver exceptional efficiency at low
power levels and low quiescent current without the
need for external voltage regulators or converters.
The device is manufactured using advanced InGaP-
Plus^TM HBT technology offering state-of-the-art
reliability, temperature stability, and ruggedness.
Three selectable bias modes that optimize efficiency
for different output power levels and a shutdown
mode with low leakage current increase handset
talk and standby time. A “daisy chainable” directional
