2.3 HEAT SINKING

The NuPower C20R01 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 12 VDC fan‐cooled

heatsink is shown with the NuPower C20R01 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).

3 SETUP AND OPERATION

This section provides specific details for proper operation of the NuPower C20R01 module. Following

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

3.1 POWER SUPPLY REQUIREMENTS

TooperatetheNuPowerC20R01,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6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(4400MHzto4900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 C20R01

TheNuPowerC20R01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 C20R01 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C20R01wasdesignedfor+28VDCoperation.
