We are facing Sensitivity issues in our designed board  which had AD9361.
This board was designed based on some other reference board which also have Ad9361.

Only difference between Reference Board and Our designed board is AD9361 Rx Port utilisation. Reference Board is using Port C whereas we are using Port A in receive direction.

We are 18 dB off in sensitivity with respect to reference board.

1. We need a quick input on RF receiver performance difference between Port A and Port C.
2. Additional changes or considerations required to use Port A (like calibration etc.) instead of Port C.

Quick pointers or help will be really appreciated.
