If you look at the way the power is supplied to and output is taken from an MMIC there's no way that I can see that they could go all the way to DC as there's always a capacitor in the output ...
I got all excited a while back when I considered an MMIC for a project because the spec said DC-xGHz. Sadly the specified circuit for using it meant there's no way it could get the DC, though a large output capacitor in parallel with a RF cap would allow audio to GHz. Hmmm where did I leave the 1 MegaFarad capacitor.
