SWRZ071D May 2017 – December 2020 AWR1243
TX1 to TX3 Phase Mismatch Variation over Temperature is Double that of TX2/TX1 and TX3/TX2 Combinations
AWR1243 ES1.0, AWR1243 ES2.0, and AWR1243 ES3.0
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.
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.
