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
