I would like to ask you experts how to design the peripheral circuit parameters of the LT6200 for the loop filter of the ADF4401A?

Hi little_rabbit: I'm not sure what filter parameters you're looking for, nor what the ADF4401A wants to see. My favorite filter is the 3rd order Butterworth shown on the back page of the LTC6240 data sheet. That's a 150kHz (-3dB) filter, but the R's and/or C's can be scaled for other frequencies.
