Hi Kenton, 
 Yes, That looks much better. I'm trying to attach the thru data but I'm unable to at this time. I will upload when the system is fixed. 
 You can down load the S-Parameter files from the link below. The thru data file is in the zip folder. You can the subtract S21 thru from the S21 magnitude of your data and you will be very close to what is shown in the data sheet.

 I measured the ADPA7005AEHZ s2p file, displayed the data with the same scaling you are using and the data lined up rather nicely.

Hi Kenton, 
 Figure 10 in the data sheet is measured with a -20 dBm input signal. Could you perform a full 2 port calibration at -20 dBm? I want to confirm the small signal results match Figure 10 from the data sheet. I want to determine if there is a measurement issue or a device issue.
