TX1 to TX3 Phase Mismatch Variation over Temperature is Double that of TX2/TX1 and TX3/TX2 Combinations

Revision(s) Affected:

AWR1843AOP ES1.0

Description:

TX3/TX1 combination exhibits a phase mismatch variation of ±6° from –40°C to 140°C whereas, TX2/TX1 and TX3/TX2 combinations exhibit a lower variation of ±3°C over the same temperature range.

Workaround(s):

In applications requiring high phase accuracy across TX channels, a background angle calibration or a 2-point calibration can be used to control phase variation over temperature.
