For calibration of ADRV9009: When doing calibration for Rx and ORx path, is there an internal switch or need a external switch to terminate to 50 Ohm?

The input port must be isolated from incoming signals. The calibration tones appear on the receiver pins. The calibration tones must be prevented from reaching the antenna by properly terminating the receiver…
You need to run the init calibrations, even if you power up the board everytime at the same frequency, since the calibration values that are stored in LUT will be lost with power off.
