Hi ,

For AWR2944 OOB demo, in MmWDemo_getDeviceRFFreqScaleFactor() it set rfFreqScaleFactor as 3.6.

Why is rfFreqScaleFactor 3.6 for automative(77GHz)? What' the rule to get ScaleFactor for 60GHz and 77 GHz?

Thanks

BRs

Hi Bruce,

RF frequency scale factor is 2.7 for 60GHz device and it's 3.6 for 77GHz device. This value comes from the ICD "C:\ti\mmwave_mcuplus_sdk_04_07_00_01\mmwave_dfp_02_04_17_00\docs\mmWave-Radar-Interface-Control.pdf"
