AN-1039: Carrier suppression frequency dependence

I wonder as in AN-1039, (Figure 7. Variation of LO Leakage and Sideband Suppression vs. Frequency after Nulling Midband), which is the physical explanation of the frequency dependance for the carrier suppression.

Does mixers exibit different isolation from LO to output according to the level and frequency of the baseband signals?
