Interfacing ADL5375 with ADF4351: LPF design

Category: Hardware

Dear supporter,

on pag. 23 of ADF4351 datasheet I found the interfacing scheme between ADF4351 and ADL5375.

Could you please suggest a LPF design to differentially interface the two devices when the ADF4351 is working with an 800 MHz RFout and a REF sinusoidal signal of 100MHz.
I am interested in removing the harmonics on the RFout, in particular the 900MHz harmonic that could be detrimental for the system.

Thank you
