AD9361 Tx spurious at +/- 4 MHz from RF

I am looking into AD9361 Tx spectrum and what I observe is two unwanted spurious components at +/- 4MHz from RF carrier (CW).


The LO is set to 100 MHz and the BB is at 1 MHz - thus the RF carrier is at 101 MHz. I observe spurs at 97 MHz and 105 MHz - approx. 30dB lower than the power of RF carrier. 


This issue is mentioned few places at the Wiki, however the applied solution does not appear to be fully clear. Anyone that observed and solved this issue?
