Go to the following
website: http://tonnesoftware.com/. There is a program called ELSIE,
that you can use to design the filter you are looking for.

Try the filter companies, but be ready to pay some
big money since it will be a custom design. You be better off designing
it yourself, it would only comprise of 5 surface mount parts at best.

You can always use DSPs. Have you actually tried searching
on Digikey for such a part? If it's not there, you can always use Google.
I found this filters site through it http://www.ana-tech.com/.

I take that
DSP quote back. I don't know much about it, but I remember my friend
telling me that the frequency that you can sample is only as good as
the processor speed. I don't think they have fast enough DSPs that can
sample a 100 MHz signal. Anyone can shed a light on this? Remember,
I'm clueless with DSPs.

Hi Amimar,
A bandpass filter at this frequency should be relatively
simple to design. Once you have designed it and calculated the L and
C values you need you should check the coil craft website for the inductors
www.coilcraft.com. For the capacitors, try AVX (www.avx.com). Coil craft
will probably supply you with a small quantity of free inductors. Upon
finding the appropriate cap from AVX you may order it online from Radio
Spares (rswww.com) etc. These components are reatily available.
Good luck
