Ok - I understand how it works now.  The one remaining question is how injecting DC into the output side (IF pin) of the mixer (as you have it drawn) would unbalance the mixer? Doesn’t this look like a short circuit to the DC? I would have thought you would connect the DC to the LO input to have current flowing through the diodes?
