AD9914 Anti-Alias and Inverse Sinc Filters

We are working on a design using the AD9914, clocked at its maximum speed of 3.5GHz, so need an anti-alias low-pass filter with a cut-off at around 1.4-1.5GHz.  The AD9914 also lacks built-in sinc correction so an inverse sinc filter will also be useful.

 

Are there any recommendations or suggested designs for an AD9914 output filter circuit?  (Unfortunately the AD9914 evaluation board has no output filtering at all so I can't use that as a starting point. )
