Unfortunately, using a low pass after the divider will not
prevent the down-mixing. The down-mixing happens as an inherent
property of digital circuits. Any filtering you do afterwards
will be too late. If you want to have low noise, then the only
way is to produce a non-square wave signal. Or in other words:
use a divider built from harmonic mixers*.
