PRODUCT DESCRIPTION
TheALT6702 HELP4TM PA is a 4th generation
HELPTM product for LTE and WCDMA devices
operating in UMTS PCS (Band 2) and for CDMA
devicesoperatinginBandClass1andBandClass
14.This PA incorporatesANADIGICS’ HELP4TM
technology to deliver exceptional efciency at low
powerlevelsandlowquiescentcurrentwithoutthe
need for external voltage regulators or converters.
ThedeviceismanufacturedusingadvancedInGaP-
PlusTM HBT technology offering state-of-the-art
reliability, temperature stability, and ruggedness.
Threeselectablebiasmodesthatoptimizeefciency
for different output power levels and a shutdown
mode with low leakage current increase handset
talkandstandbytime.A“daisychainable”directional
couplerisintegratedinthemodule,thuseliminating
theneed ofan externalcoupler.Theself-contained
3 mm x 3 mm x 1 mm surface mount package
incorporatesmatchingnetworksoptimizedforoutput
power, efciency, and linearity in a 50 Ω system.
