Hi

For one of my customers that moved from AD9361 to AD9363 and getting lower rx sensitivity.

Same board, same peripherals, sam management platform and interfaces.

See table attached for the percentage of the jperf in the sensitivity test.(new rf-AD9363 results in the RIGHT SIDE of the table, AD9361 results in the LEFT SIDE ).

All units are in DBm. also see that the second channel  RF2 is showing much worse sensitivity levels  with the  AD9363.

 

Please advise what/where to look for...

The Configuration registers are the same for both AD9363/1.

 Thanks

Freddy
