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.

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.

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

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/

HELP3
TheAWU6608 power amplier module is based on
ANADIGICS proprietary HELP3™ technology. The
PA is designed to operate up to 17 dBm in the low
powermode,thuseliminatingtheneedforthreegain
state, while still maintaining low quiescent current
andhighefciencyinlowandmediumpowerlevels.
ThePA canstillbeoperatedas3gainstate device
if the customer chooses to. The directional “daisy
chainable”couplerisintegratedwithinthePAmodule,
thereforethereisnoneedforexternalcouplers.
TheAWU6608 has an integrated voltage regulator,
which eliminates the need for an external constant
voltage source. The PA is turn on/off is controlled
by VEN pin.A single VMODE control logic (VMODE1) is
neededtooperatethisdevice.
The DG09 power distribution (gure 15) highlights
theneedtoimprovethecurrentconsumptioninlow
andmediumpowerlevel.TheAWU6608isdesigned
tooperateupto17dBminthelowpowermodewith
verylowquiescentcurrent.Currentconsumptionfor
AWU6608isalsoplottedinthegure5.
AWU6608 requires only two calibration sweeps for
systemcalibration,thussavingcalibrationtime.
Figure16showsoneapplicationexampleonmobile
board. C1 and C2 are RF bypass caps and should
be placed nearby pin 1 and pin 10. Bypass caps
C9andC5maynotbeneeded.Alsoa“T”matching
topology is recommended at PA RFIN and RFOUT
portstoprovidematchingbetweeninputTXFilterand
Duplexer/Isolator.
