PRODUCT DESCRIPTION
The ALT6708 HELP4TM PA is a 4th generation HELPTM
product for LTE and WCDMA devices operating in
UMTS900 (Band 8) . This PA incorporates ANADIGICS’
HELP4TM 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-
PlusTM 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 coupler is
