ANA#35A

Low inter-RX isolation between adjacent channels (RX1/RX2 or RX3/RX4)

Revisions Affected

AWR294x ES1.0, ES2.0

Details

RX1/RX2 and RX3/RX4 pairs exhibit low interchannel isolation of 25dB .

Workaround

No workaround is available.

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