Revision History

ANA#34A

Low inter-TX isolation between adjacent channels (TX1/TX2 or TX3/TX4)

Revisions Affected

AWR294xES1.0 ONLY

Details

TX1/TX2 and TX3/TX4 pairs exhibit low inter-channel isolation (22dB) in AWR2944 ES1.0 device.

This number has improved to >30dB in AWR2944 ES2.0 device.

Workaround

If the isolation is still limiting the angular accuracy, zero angle calibration can be extended to multiple angles to calibrate the antenna gain & phase mismatch to improve the angular accuracy.

Silicon Fix is provided in AWR2944 ES2.0.
