Hi, If I understand correctly you are upconverting low power levels to mimic the channel losses, is it right?, Why don't you upconvert a higher power level to avoid the problems of LO leakage and then you put a resistive attenuator fixed or variable after the mixer to mimic the losses?, it's the only solution that I can think about that doesn't imply a change of the mixer. Hope it helps,
