The errata states:
"ANA#13B Phase Mismatch Variation Across Temperature in TX3/TX1 and TX3/TX2 Combinations are higher than that of TX2/TX1 Combination
Revision(s) Affected: IWR6243 ES1.0 and ES1.1
Description: TX3/TX1 and TX3/TX2 combinations exhibit a higher phase mismatch variation across the complete recommended operating temperature range per the data manual as compared to TX2/TX1 combination over the same temperature range.
Workaround(s): In applications requiring high phase accuracy across TX channels, a background angle calibration can be used to control phase variation over temperature"
Is it possible to get some more information on this? How big is the error? Can you provide details on how the " background angle calibration" is supposed to work
