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.
