PRODUCT DESCRIPTION
The ALT6704 HELP4^TM PA is a 4th generation HELP^TM
product for LTE and WCDMA devices operating in
UMTS1700 (Band 3, 4, 9, 10) and for CDMA devices
operating in AWS/KPCS 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
