AnHDMRFModuledoesthefollowing:
• interfaceswithoneHostDART-eitherClassicorSuperDART,oroneCDIU
• supportstwonon-contiguousRFslicesupto35MHztotalbandwidthinaDualorMIMOconfiguration
• supportsfullbandwidthinaSISOconfiguration,upto75MHz
• supports20Wperband/PathinaDual/MIMORFModule
• supportsupto40WRFoutputpowerinaSISORFModule.
ThecomponentsofaPRUHDMRFModulearedependentonthemoduletype,aslistedinTable12.
