Varactor modeling in ADS

Dear,

I'm trying to model a varactor in ADS 2006 update3. I got SPICE model parameters from the data sheet of the varactor that I want to use.

First, I typed the value of the SPICE model parameters in DIODE model of ADS, but it didn't work. Moreover, I couldn't find any way to apply the reverse voltage to increase the capacitance of the varactor.

Is there any body who can explain how to model an varactor in ADS?

please take a look at

The file i have uploaded there contain a tutorial how to model varactor diode using spice model and how to test the model. Hope that help.

u can apply the control voltage by using RF chock

so this inductor will be very high impedance at RF
