AD9957+ADF4351+ADL5801

Hi, everyone!

 

I use AD9957+ADF4351+ADL5801 in an up-conversion application. The AD9957 generates a 50 MHz intermediate frequency signal which is sent to the RF port of the ADL5801; The ADF4351 provides a  1700 MHz LO, and the ADL5801 mixes the two signals. Does this scheme make sense? If OK, then how do I tune the complents of the ADL5801 to get a right matching? It seems that the ADL5801 works better in down-conversion apllication than the up-conversion application.

 

Thanks very much!
