PRODUCT DESCRIPTION
The ALT6701 HELP4
TM
PA is a 4th generation HELP
TM
product for LTE and WCDMA devices operating in
UMTS2100 (Band 1) and for CDMA devices operating
in Band Class 6. 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
