ADF4360-9 L1/L2 inductor selection

Hello,

 

I plan to use an inductor for L1=L2 which has a higher Q than the Coilcraft 0603CS and 0805CS series mentioned on the data sheet.  Since the inductor Q is higher then the Rp is higher.  Is it then recommended to change the 470 ohm resistor value (in parallel with L1 & L2) to keep the overall Q the same?  In this case, the 470 ohm value would need to decrease slightly.

 

Thanks,

Eric
