OPA847: Noise figure for op amps

Part Number: OPA847


I want to use OPA847 as a gain block for a receiver between 50 to 500KHz.

I am using Keysight ADS with the workspace found on TI website, and simulating the noise figure using the spice model with ADS S parameter solver. How accurate are the results? Does anyone has a spreadsheet for calculation of noise figure from op amp noise parameters?
