In page 14 of HMC787A data sheet, the 2x2 spurs = 89dBc for -5dBm, 3100M RF in, 6100M LO and IF=3000M. dBc is wrt 1x1 conversion loss = 0dB in table.
That implies IIP2=+84dBm; this is not believable. What am I missing?
Please look at figures 9,12, 22 and 24 which seems to correlate with 2x2 spur value that the IIP2 can peak above 80dBm at certain RF and LO frequencies.
