Noise of AD8331 LNA in spice simulation

Hi,

I am using the official AD8331 LNA Model in LTSpice and get much higher input referred voltage noise than I would expect from the datasheet. Also the frequency characteristics using impedance matching is not consistent to the datasheet. Are there known issues or limitations of the simulation model causing these effects?
