Use of SAW filter for AC Coupling

Hi,
So I have a SAW filter that is already matched to 50 ohms input/output.
From the antenna can I place a SAW filter immediately before the Low Noise Amp or will I need to place a coupling capacitor?
Similarly I have another component that has a .75 V pk-pk AC signal on top of a 1.3 V DC signal. Can I use a SAW filter alone or will I need a coupling capacitor to remove the DC? My main concern is that the SAW filter won't work under a DC bias.
