HMC943APM5E output

Good afternoon!
We are using HMC943APM5 to amplify the ADF5901 transmitter signal. 
As shown in Figure 30 datasheet, at an input of 8 dBm, the output of the HMC943APM5 will be> 30 dBm.
What is the noise level at the output of the HMC943APM5 when the ADF5901 radiation is off (RFin = 0)?
What are its spectral properties? Can we expect> 8 dBm at the output?
