How does this MMIC work?
In general MMIC amplifiers are only limited in the low frequency range by your blocking capacitors.  To size them, just make sure the capacitive reactance (1/(2 * pi * f * c) at your frequency is much less than 50 ohms.  In recent years there have been some built for very high frequencies that don't go down to DC, but if the data sheet doesn't mention this then you're probably OK.
The inductor in the VCC line is there to keep you from dissipating your signal power in the biasing resistor. Here what you want to do is make sure the inductive reactance at your frequency (2 * pi * f * l) is much bigger than 50 ohms.
