TX1 to TX3 Phase Mismatch Variation over Temperature is Double that of TX2/TX1 and TX3/TX2 Combinations
IWR2243 ES1.0, ES1.1
TX3/TX1 combination exhibits a phase mismatch variation of ±6 degrees across the complete recommended operating temperature range per the data manual whereas, TX2/TX1 and TX3/TX2 combinations exhibit a lower variation of ±3 degrees over the same temperature range.
In applications requiring high phase accuracy across TX channels, a background angle calibration can be used to control phase variation over temperature.
