2.3 HEAT SINKING
TheNuPowerL60T01isofferedasastand‐alonemoduleorwithanaccessorykit
(p/nNW‐PA‐ACC‐KT03),whichincludesa28VDCfan‐cooledheatsinkandrequisitepowercable.[Thekit
alsoincludesanupgradedmoduleinterfacecableassembly,labeledandterminatedwithbananaplugs.]


Figure 3: The NuPower PA Kit offers “out‐of‐the‐box” operation for the user. The 28 VDC fan‐cooled
heatsink is shown with the NuPower L60T01 mounted.




Caution:Theuseofexternalheat‐sinkingisrequiredespeciallyforthoseapplications
requiringhighdutycycleoperation(e.g.continuouswave)orforextendedon‐timetesting.
Operationwithoutaproperheatsinkundertheseconditionswillcausepermanentdamage
totheproductandwillvoidtheproductwarranty.

Themaxoperatingtemperatureis85˚C(baseplate).

3SETUP AND OPERATION
ThissectionprovidesspecificdetailsforproperoperationoftheNuPowerL60T01module.Following
theseguidelineswillpreventdamagetothepoweramplifierorexternalequipment.
3.1 POWER SUPPLY REQUIREMENTS
TooperatetheNuPowerL60T01,ensurethatthepowersupplyhasadequateoverheadtosourcethe
currentdemandoftheRFpoweramplifier.Thepowersupplysourcemustprovideatypicalvoltageof
+28VDCwithgreaterthan5ampscapability.
3.2 CONNECTING A PROPER LOAD TO THE ANTENNA TERMINAL
TopreventdamagetothePA,theantennaterminalmustbeterminatedintoa50Ωload.Examplesofa
properloadinclude:

Directlyconnectingtoanantennaspecifiedforthefrequencyrange(960MHzto1390MHz).
ConnectingtoaninappropriateantennamayresultindamagetothePAmodule.
Connectingtoaproperantennathrougha50Ωtransmissionlineorcoaxialcable.Avoidusing
damagedcablesorcorrodedconnectorswhileattachingtheunittoanantenna.
Terminatingtheantennaterminalintoa50Ωpowerattenuatorwithminimum20dB
attenuation.
ConnectingtoaloadcapableofdissipatingtheRFpowerfromthePAmodule.Loadscapableof
handling50Watts(min)arerecommended.
3.3 POWERING‐UP THE NUPOWER L60T01
TheNuPowerL60T01mustbeterminatedtoaproperloadbeforepowerisapplied.RefertoSection3.2
forthespecificationsoftheproperload.AfterthePAisproperlyterminated,theinterfacecablecanbe
connectedtotheunitandpowercanbeapplied.ThePAisnowreadyforoperation.
3.4 TRANSMIT TURN‐ON TIME

Caution:DonotapplytransmitdatauntilthePAmoduleisatfullpower.Thiswillprevent
lossofdataatthebeginningofamessage.

TheNuPowerL60T01isatfullpowerapproximately1µSaftertheRFEnablelinegoeslow(ground).
Therefore,transmitdatacanbeappliedtotheinputafter1µSwithoutlossofdata.
3.5 RF OUTPUT POWER VS. SUPPLY VOLTAGE
TheNuPowerL60T01wasdesignedfor+28VDCoperation.
