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. 73, Rik ON7YD >Dave, Graham and I used a MAR3 pre-amp in Guernsey and found it overloaded >with the large signal from Lessay. The MAV11 is rated at 60mW output and may >be a better choice if you can spare the current. > > >73 > >David. G0MRF > >
