Hello Marcus,

I did the calibration but it didn’t change the results. There is still LO leakage on transmitter. I attached the generated cal file location as a figure.


So, I"m just looking again at your Spectrum Analyser traces.

It looks like there's a little bit better than 30dB LO suppression in your TX signal.  That's not splendid, but it's not horrible, either.

I would suggest using offset tuning to move the LO leakage out-of-band with respect to your carrier signal.
