ADL5801 noise figure at 6 GHz (vs ADL5380)

Looking at the ADL5801 datasheet, page 4 indicates a SSB noise figure of 16.2 dB at 5.5 GHz.

However, figure 56 on page 17 indicates a noise figure of 19.1 dB.  Which is correct?

 

As far as I can see, both are measured under the same conditions (VS = 5 V, TA = 25°C, VSET = 3.6 V, IF = 153 MHz).

 

I am trying to work out whether or not this mixer has a better noise figure over the range 5-6 GHz than the ADL5380, which has a DSB NF of 14 / 17 dB at 5 / 6 GHz respectively according to figure 37 on 14 of the ADL5380 datasheet -> SSB NF of 17-20 dB over 5-6 GHz RF input.

 

BTW, I know that the NF in the ADL5380 datasheet is specified as DSB due to this thread: http://ez.analog.com/message/87086#87086

 

Many thanks.
