Does AWR1843 operate on 77-81GHz, 76-77GHz or both? Is the bandwidth which Radar sensor operates on depend on the Firmware?

In our case, we use automotive lab demo MRR, it seems the Radar sensor operates on 76-77GHz.

Kind regards

Please check in the Radar Interface Control document the API that configures the VCO

C:\ti\mmwave_dfp_01_02_06_03\docs\mmWave-Radar-Interface-Control.pdf

Please see Table 5.23: AWR_PROFILE_CONF_SB, PF_VCO_SELECT.

The configuration is part of the profile configuration: rlProfileCfg.pfVcoSelect

I don't see it updated by the MRR code, so it should be "0", which corresponds to VCO1 76-78GHz

thank you
