Most op-amps can go well over over 100kHz, so the frequency shouldn't be a problem. You can build an [u]amplifier using an op-amp[/u] with just the op-amp; and two resistors. Plus you need a bipolar power supply and a bypass cap (~0.1uF) on both supplies.
Do you have any idea how much gain you need? (It's probably going to take some experimentation.)
