s-params

Can anyone recommend a program that will turn s-parameters into R-L-C element equivalents?
We use a lot of "RF" parts, in fast time-domain circuits, so s-params aren't much help in simulation. I can eyeball S11 of a fet and guestimate gate capacitance, but that's about as far as I can go.
We like the Avago phemts, because they at least provide some DC curves on their data sheets. Lots of people don't even do that.
Just now, I want to estimate how much the ni input of a current-mode opamp will load my signal source. But the problem recurrs.

I love to cook with wine. Sometimes I even put it in the food.
My problem with s-parameters in large signal circuits was that they changed with current.
Jim's web-site doesn't deal with that particular problem.

Try this:
I was looking at that- it would be nice to have a SPICE model of some of the minicircuits components but not for $7K. Someone should moonlight translating models for $50 or $100 a shot or something like that.
