2 Product Description

TheTunerGeniusXL™(TGXL™)isa2000Wautomaticantennatunerwithfullfrequencycoveragefrom1.8MHz

to54MHz.ItisdesignedtomatchanantennasystemwithanSWRofupto10:1automatically.Thetuneris

builtto"broadcastindustry"commercialstandardswitha1500W100%IntermittentCommercialandAmateur

Service(ICAS)powerrating.Theabsolutemaximumpealpowerhandlingcapabilityis2000W.

AllTunerGeniusXLfunctionsarecontrolledeitherfromthefrontpanelofthetunerorfromaWindows

computersoftwareapplication.UsingtheWindowsapplicationallowstheTGXLtobeinstalledawayfromyour

operatingpositionorinanothergeographiclocationovertheInternet.Additionally,high‐precisionpeak

respondingRFpowerandSWRmeterdisplaysareprovided,eliminatingtheneedforaseparatePower/SWR

meterdeviceinyourshack.

TheTunerGeniusXListightlyintegratedwiththePowerGeniusXL™(PGXL™)RFamplifierandallFLEX‐6000™

seriesHFtransceivers.IntegrationisachievedusingastandardLAN‐basedAPIandcommunicationsprotocol.

TheAPIispublishedsoyoucanwritesoftwareapplicationsforyourtuner.

TheTunerGeniusXLiscompatiblewithanymodernHFradioonthemarkettoday.Whenusedinconjunction

withaPowerGeniusXLandaFLEX‐6600orFLEX‐6700transceiver,youhaveacompetitive,fullyfunctional

SO2R(singleoperator,two‐radio)radiosportstation.Inaddition,supportforSmartLinkandmultiFLEX™

operationprovidesfrustration‐freemulti‐clientremoteoperation.

3 What is an Antenna Tuner?

AnantennatunerisadeviceintheRFsignalpathbetweenthetransmitter(ortransmitter+amplifier)andits

antennatoimprovepowertransferbetweenthembytransformingtheimpedancepresentedatthe

transmitter'santennafeedoutputtoacompatiblevalue.Thisimpedancechangeprotectsthetransmitterfrom

thepotentiallydamagingeffectsofhighreflectedpower,allowingthetransmittertoavoidreducing(folding

back)powertoprotectitself.Anantennatunerisespeciallyusefulwhentheantennaandfeedlineimpedance

isunknownandcomplex.

It'simportanttounderstandthatthetunerdoesnotchangetheactualSWRoftheantennaandfeedline.

Instead,ittransformstheimpedancepresentedtothetransmitter.

4 Circuit Description



Page8of72

TunerGeniusiselectricallyimplementedasapi‐networktunerwiththreevariableelements;aseriesinductor

withtwocapacitorstoground:oneattheinputandtheotherattheoutput.Apinetworkisidealformatching

therelativelylow50Ωimpedanceofatransmitterandrelativelyhighandunknownimpedancesantenna

systempresentforacurrentoperatingfrequency.Furthermore,becausethematchingcircuitalsoformsalow‐

passfilter,itprovidesbeneficialharmonicsuppressionbeyondthatprovidedbytheexciterandamplifier.

ThetunerisasystemofdiscreteLCcomponentswhichareswitchedintoandoutofthematchingcircuitbya

microcontroller.ThecombinationofdiscreteLorCcomponentsdetermineseachnetworkelement'svalue.

Eachelementcanbeoneof255possiblevalues.Thishighlygranularsteppedapproachprovides2553

(16,581,375)possiblematchingcombinations.

4.1 Tune

Wheninstructedbytheoperator,themicrocontrollerkeysthetransmitterandexecutesanalgorithmthat

quicklyvariesthevalueforeachelementofthematchingnetwork.Foreachvalue,theoutputofadirectional

couplerissampledandusedtosearchforatargetimpedancematch.

Onceamatchsolutionisfound,thefrequencyanddatanecessarytorecallthematchingnetwork'selement

valuesarestoredinanon‐volatilememorylocation.Whentheoperatornexttransmitsonafrequencywithin

10kHzofastoredsolution,thevaluesrequiredtoreconstitutethepinetworkelementvaluesarerecalledand

appliedtothecircuit.

4.2 Transmit

ThemicrocontrollersamplesthedirectionalcouplertopresentaccurateforwardpowerandcalculatedSWR

duringtransmissions.

4.3 Receive

Duringreceive,thetunercanoptionallybypassthetunedmatchingcircuit.
