HMC835 Reference Input

Question asked by rmountain on Nov 11, 2016

On the HMC835 Reference Input, The REF Input characteristics list the input range as -6 to +12dBm, Table 4 lists the recommended 100MHz sinewave clock amplitude as +5 to +15dBm, Figure 25 seems to indicate that the optimum FOM occurs at about -3 dBm and the plot does not go beyond +1dBm.  This leads me to believe that my optimum clock amplitude should be closer to 0dBm then +12/+15dBm, can you please clarify this?  Thanks.
