2.3 HEAT SINKING

The NuPower 12D05A 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 12D05A 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maximumoperatingtemperatureis85˚C(baseplate).

3 SETUP AND OPERATION

This section provides specific details for proper operation of the NuPower 12D05A module. Following

theseguidelineswillpreventdamagetothepoweramplifierorexternalequipment.

3.1 POWER SUPPLY REQUIREMENTS

TooperatetheNuPower12D05A,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3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 (800 MHz to 2000 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 12D05A

TheNuPower12D05A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 12D05A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12D05Awasdesignedfor+28VDCoperation.
