I would like to know if it is possible to reduce the LO Leakage of AD-FMCOMMS1-EBZ.
By consulting the Application Note AN-1039, a technique is presented but I'm not sure that it can works on this board.
The transmit channel can be optimized or calibrated to reduce the LO and the image by playing with the Phase, Offset and the Scale of the I/Q DAC.
If you use our Linux distribution, we have an option to change these values for each I and Q at any frequency for optimization. We also have calibration values stored in the memory that can be recalled for certain frequencies.
I´ve changed the DAC Offset with the auxiliary DAC and the LO Leakage was reduced around 30/40 dB.
