For AD9371, if we are using internal RF LO, do we still need to perform initial calibration for EXT TX LOL which uses external loopback to ORx?
External TX LOL is provided to improve the LOL performance when using internal LO. This calibration does not provide good performance if an external LO is provided as the TxLO. In such cases, LO leakage performance is reliant solely on the initialization calibration, and subsequently degrades.
