Analog filter before USRP?

Hello
Is a preselector needed before the USRP when receiving from antenna? May
be not. I see that there’s a CIC filter
in the USRP which is selective enough to estract a narrower band for the
GNURadio processing.
But at least I need a low-
pass filter before the USRP to get rid of strong singnals above Fs/2 (Fs
= the sampling rate).
Is this correct?

Thanks
in advance
Alberto
