In the spice model of the AD8310, the input impedance is very low, less than 1 ohm. Not on the real chip and the specs. Is there a reason ?

I use the AD8310 like in the specs page 14, fig 27 as a wide band detector. I use Multim to simulate the whole circuit, with an input wide band filter in front of the detector AD8310. Thereal  circuit works perfectly, but the simulation is wrong, because the input impedance of the AD8310 crush the output of the filter.

Have an idea ?
