You should do lowpass and highpass LC filters in series.

What application you need for such a wideband with SAW filter ?
 

Re: SAW filter [hlp]

Depend what is the application and how much is the in-band and out band attenuation (you can use some ceramic filter).

hi,

Try filters from MINICIRCUIT they probably have what you need (LPF+HPF)

I think it is very important as follows:
1. how much is your out band attenuation?
2. Whether enough is your free space?

If use LPF+HPF to do a filter, i think need huge dimension to reach a acceptable performance.
