I am using AD9914, output 50~250MHz signal. About the output filter, how to design it, and whether or not could design a RC band-pass filter. Is there any reference design.
We do not have filter reference designs, there are filter design tools available which you could use, I do not believe any one of them stands out above the others as preferable. An RC band-pass filter would be fine to use with the AD9914.
