PRODUCT DESCRIPTION
The AWT6621 HELP4TMPAisa4thgenerationHELPTM
productforWCDMAdevicesoperatinginUMTS2100
(Band 1) and for CDMA devices operating in Band
Class6.ThisPAincorporatesANADIGICS’HELP4TM
technology to deliver exceptional efciency 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efciency
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integratedinthemodule,thuseliminating
theneedofanexternalcoupler.Theself-contained
3 mm x 3 mm x 1 mm surface mount package
incorporatesmatchingnetworksoptimizedforoutput
power, efciency, and linearity in a 50 Ω system.

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure
to absolute ratings for extended periods of time may adversely affect
reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric performance is guaranteed only
overtheconditionsdenedintheelectricalspecications.
Notes:
(1) For operation at 3.2 V, POUT is derated by 0.5 dB.
