PRODUCT DESCRIPTION
TheAWU6608HELP3TMPAisa3rdgenerationWCDMA
product for UMTS handsets. This PA incorporates
ANADIGICS’ HELP3TM technology to provide low
powerconsumptionwithouttheneedforanexternal
voltage regulator.A “daisy chainable” directional
couplerisintegratedinthemodulethuseliminatingthe
needofexternalcouplers.Thedeviceismanufactured
on an advanced InGaP HBT MMIC technology offering
state-of-the-art reliability, temperature stability, and
ruggedness. There are two selectable bias modes
that optimize efciency for different output power
levels,andashutdownmodewithlowleakagecurrent,
whichincreaseshandsettalkandstandbytime.The
self-contained3mmx3mmx1mmsurfacemount
packageincorporatesmatchingnetworksoptimizedfor
outputpower,efciency,andlinearityina50Ωsystem.

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 Vc c = +3.2 V, Po u t is derated by 0.5 dB.

APPLICATION INFORMATION
To ensure proper performance, refer to all related
Application Notes on theANADIGICS web site:
http://www.anadigics.com
Shutdown Mode
The power amplier may be placed in a shutdown
mode by applying logic low levels (see Operating
Rangestable)totheVENABLE and VMODE1voltages.
Bias Modes
ThepowerampliermaybeplacedineitheraLowBias
modeoraHighBiasmodebyapplyingtheappropriate
logic level (see Operating Ranges table) to VMODE1.
TheBiasControltableliststherecommendedmodes
of operation for various applications. VMODE2 is not
necessaryforthisPA.
Twooperatingmodesareavailabletooptimizecurrent
consumption.HighBias/HighPoweroperatingmode
isforPOUTlevels>16dBm.Ataround17dBmoutput
power,thePA can be “Mode Switched”to Medium/
Low power mode for lowest quiescent current
consumption.
