AD8338 compression?

I need to figure out how much power I can input into the AD8338, but the 1dB compression point nor the IP3 is listed on the datasheet. Is there anyway to figure this out without actually having the chip in front of me and increasing input power til it goes nonlinear? I know the 1dB compression point is dependent on the gain, which is variable in this case, so honestly I'm not even sure if it's possible to actually have one. Any clarification on this topic would be greatly appreciated.

 

Also, I need the noise figure for the chip, but they give the noise density on the datasheet and I don't really understand how to interpret it.
