The ALT6702 HELP4
TM
PA is a 4th generation
HELP
TM
product for LTE and WCDMA devices
operating in UMTS PCS (Band 2) and for CDMA
devices operating in Band Class 1 and Band Class
14. 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
