hello everybody
first of all sorry for my not perfect english...
i need to measure the signal sended from a TAG (transponder) and receive
from an RFID antenna at 134 KHz (LFID) with a digital oscilloscope bu
this signal is too low for the resolution of the oscilloscope. and so
need a preamplifier to put up that signal... i have thought to use a
Op-amp but i think a normal one is not good in this case because it has t
be a particular one for LFID system (for coupling, adaptation etc et
etc).

everyone can suggest me something?

I suggest that you buy a PAR (Princeton Applied Research Corporation)
model 113 amplifier.
