MA46H071 Varactor model for ADS ?

Hi,

I wanted to model a MACOM MA46H071 in ADS.

I have the Cjo and other values. I just can't get the right set of C values for a given bias.

Can anyone help me out with it ?

There is some equations for calculate the C values. You can find the equations from the datasheet or search it. Sorry I forget it.
