SNR degradation at 60 GHz in the presence of strong near range reflector

Revision(s) Affected

IWRL6432AOPES2.0

Details

There is a non-linearity of the synthesizer when crossing 60GHz which causes increased noise floor at RX output in the presence of a strong near range reflector.

Workaround

Chirps with large RF bandwidth (> 1.5GHz) have negligible noise floor impact. For lower bandwidth chirps, avoid 60GHz.
