Description
TheLR68NA‐Cmoduleissub‐GHzradiotransceiversareidealforlongrangewireless
applications.ThesedevicessupportLoRa®modulationforLPWANusecasesand(G)FSK
modulationforlegacyusecases.Thedevicesarehighlyconfigurabletomeetdifferentapplication
requirementsutilizingtheglobalLoRaWAN®standardorproprietaryprotocols.
ThedevicesaredesignedtocomplywiththephysicallayerrequirementsoftheLoRaWAN
specificationreleasedbytheLoRaAlliance™.
Theradioissuitableforsystemstargetingcompliancewithradioregulationsincludingbutnot
limitedtoETSIEN300220,FCCCFR47Part15,ChinaregulatoryrequirementsandtheJapanese
ARIBT‐108.Continuousfrequencycoveragefrom150MHzto960MHzallowsthesupportofall
majorsub‐GHzISMbandsaroundtheworld..
Architecture
TheLR68NA‐Cisa half‐duplextransceivercapableoflowpoweroperationin the150‐960MHz
ISMfrequencyband.Theradiocomprisesfourmainblocks:
1.Analog Front End: the transmit and receive chains, as well as the data converter interface to
ensuingdigitalblocks.TheLR68NA‐Ctransceiveriscapableofdeliveringupto+14dBmunderthe
batterysupply.
2.DigitalModemBank:arangeofmodulationoptionsisavailableintheLR68NA‐C:
LoRa®Rx/Tx,BW=125‐250‐500kHz
LoRa®SF=5‐6‐7‐8‐9forBW=125kHz
LoRa®SF=5‐6‐7‐8‐9‐10forBW=250kHz 
LoRa®SF=5‐6‐7‐8‐9‐10‐11forBW=500kHz
3.DigitalInterfaceandControl:thiscomprisesallpa yloaddataandprotocolprocessingaswellas
accesstoconfigurationoftheradioviatheSPIinterface.
4.PowerDistribution:twoformsofvoltageregulation,DC‐DCorlinearregulatorLDO,areavailable
dependinguponthedesignprioritiesoftheapplication.
