Hi David,

did you test the MAV11 on 136kHz ? 
Mini-Circuits gives a frequency range of 50-1000MHz (while the MAR, ERA,
RAM series start at DC), so it may have a internal C that limits the lowest
frequency.

The datasheets gives a IP3 of +30dBm, so it you can get any gain out of it
at 136kHz it should be OK.
