ADA4350: Spice simulation

I have a question about the ADA4350 SPICE Model's simulation.

I am simulating the FET amplifier in ADA4350.


The simulation result of figure was simulated with the circuit of Figure 51.

Vs = ±5V, Vout = 100mVp-p, G = +2, Rf = 1KΩ, Cf = 3pF


In the simulation result, the peak of the frequency response is different from the data sheet.


As for Figure 68, the simulation result was different from the characteristic of the data sheet.


Is the spice model of ADA4350 wrong?

Best Regards,
