SAFETYOPERATIONINSTRUCTIONS
BEFOREUSE
Reviewthismanualandinsurethatallconditionsarecompatiblewiththe
amplifier'sspecifications.Safeoperationmaybeimpairedifthisequipmentis
notusedasintended.

GENERALDESCRIPTION
Thissymbolismarkedinthemanualanddenotesimportantsafetyoperation
instructions.Pleasereadcarefullybeforecontinuing.
Thisequipmentissuitableforawidevarietyofscientific,industrial,
laboratoryandcommunicationapplicationswherehighlevelsof
electromagneticRadioFrequency(RF)energyarerequired.Therefore,the
outputoftheamplifiermustbeterminatedtoanappropriateload,suchas
ahighpowerattenuator,dummyload,acommunicationorradiation
antenna.Usermustinsurethatradiatedenergydonotviolateregulatory
levelsofelectromagneticinterference.

PROTECTIVEGROUND
Thissymbolismarkedontheequipmentanddenotesprotectiveground
terminal.
Thisamplifierincludesprotectivegroundterminal.Theequipmentshouldn't
beusedifthisprotectionisimpaired.Thesuppliedpowercordmustbeused
alongwithanuninterruptedexternalpowersource.

HAZARDOUSLINEANDRFVOLTAGES
Thissymbolismarkedontheequipmentwheredangerousvoltagesare
present.Useextremecaution.
BothRFinputandoutputconnectorsshouldbeterminatedpriortothe
applicationoftheexternalACsource.Otherwise,contactwiththeRF
outputcenterpincanbedangerous.PlacetheamplifierintheOFFposition
priortoconnectinganddisconnectingRFoutputload.

ELECTROSTATICDISCHARGE(ESD)
ThissymbolismarkedontheequipmentwhereESDsensitivedevicesare
present.Donothandlewithouttheproperprotection.

MAINTENANCE
Maintenance,repairandcalibrationmustbeperformedbyqualified
personnelonly.Contactwiththeinternalamplifiercomponentsmaybe
dangerousevenwhentheequipmentisintheOFFposition.

ThisdenotesaconditionthatmaycausedamagetotheAmplifierif
procedureisnotcorrectlyperformed.Donotproceeduntiltheindicated
conditionsaremet.

FORCEDAIRCOOLING
Donotblocktheinletandoutletoftheinternalcoolingblowers.Otherwise

OVERVIEW
TheBDAassemblyextendsthecoverageareaofradiocommunicationsinbuildingsandRF
shieldedenvironments.TheBDAhasdualRFpathstoextendcoverageintwodistinct
frequencybands.

Theunitfeatureslownoisefigureandwidedynamicrange.Itisbasedonaduplexedpath
configurationwithsharpoutofbandattenuationallowingimprovedisolationbetweenthe
receivingandtransmittingpaths.

FCCNOTE
ThisisaClassBdevice.TheproducthasbeentestedandfoundtocomplywiththeBooster

NOTE
TheManufacturer’sratedoutputpowerofthisequipmentisforsinglecarrieroperation.Forsituations
whenmultiplecarriersignalsarepresent,theratingwouldhavetobereducedby3.5dB,especially
wheretheoutputsignalisre‐radiatedandcancauseinterferencetoadjacentbandusers.Thispower
reductionistobebymeansofinputpowerorgainreductionandnotbyanattenuatorattheoutput
ofthedevice.

RFEXPOSUREWARNING

Anantennamustbeinstalledsoastoprovideaminimumseparationdistanceofatleast7.87inch(20
cm)betweentheindoorantennaconnectedtotheRFboosterandthehumanuser’sbodywithinthe

GENERALOPERATIONALDESCRIPTION

TheBDADownlinkpathreceivesRFsignalsfromthebasestationandamplifiesandtransmitsthemto
thesubscriber.TheBDAUplinkpathreceivesRFsignalsfromthesubscriberandamplifiesand
transmitsthemtothebasestation.TheUplinkandDownlinkoccupytwodistinctfrequencybands.
Seetableonpage6forlistofbandsandcorrespondingbandcodes.Frequenciesapplicabletoyour
unitwillalsobeonunit’sspecificationsheet.

Thediplexerisolatesthepathsandrouteeachsignaltotheproperamplifyingchannel.

AnAutomaticLevelControl(ALC)allowsforoutputpowerlimiting.Avariablestepattenuatorgives0–
30dBofattenuationin2dBsteps.Theuseofthesecontrolsiscoveredinthe“OPERATION”section,
laterinthisdocument.

TheMini‐BDAcanbeusedasalineamplifier.Withanoptionalexternalbias‐tee,theMini‐BDAwill
functionwithpowercomingfromtheIn‐buildingantenna.

backoftheunit.

Aoptional9‐pinD‐Subconnectorprovidesfailurealarmoutputcontacts.

TheRFconnectionsaremadeviatwotype“N”femaleconnectors.TheRFconnectorlabeled“BASE”
mustbeconnectedtotheantennapointingtowardsthebasestation.TheRFconnectionlabeled
“MOBILE”mustbeconnectedtotheantennafacingtheareatobecoveredbytheBDA.

TheRFconnectionsmustbemadethroughcableswithcharacteristicimpedanceof50ohms.

Theisolationbetweenthebasestationantennaandthemobileantennashouldbeatleast15dB
higherthantheBDAgain.Isolationlessthanthisvaluecancausegainrippleacrosstheband.

DONOTAPPLYA.C.POWERTOTHEBDAUNTILCABLESARECONNECTED
TOBOTHPORTSOFTHEBDAANDTHEANTENNAS.


1. MounttheBDAonthewallwiththeRFconnectorspointingDOWN.Usingappropriate
screwsandanchors,attachtheBDAtothewallatthefourmountingholesontheside
flanges.


2. Ensurethattheisolationbetweenthedonorantennaandtheserviceantennaisatleast15
dBgreaterthantheBDAgain.(UsethehigheroftheUplinkandDownlinkgainsreportedon
theBDAtestdatasheet).


3. ConnectthecablefromthedonorantennatotheBDAconnectorlabeled“BASE”andthe
cablefromtheserviceantennastotheBDAconnectorlabeled“MOBILE”.


4. Verifythatbothoftheattenuator’sarepositionedtoitsmaximumsetting(30dB)onthe
unit’sfrontpanel.


5. ConnectthepowercordtotheBDAandthentothepowersource.Verifythatthe“Power
ON”lampisilluminated.

