FOM new or FOM Bnew . For example, OIP3
shows low correlation with gain, frequency, BW, and Tcas . OIP3 is most
strongly correlated with Pdc, but even
this is still rather low at 20%. Therefore, an FOM to capture LNA linearity
via OIP3 could simply be created by
multiplying FOM Bnew by OIP3, as in
, IP3
FOM Bnew
L [nm] # B 0r .32 ^f0 [GHz] + 17.4h2.3
=

Tcas [K] # Pdc [mW] 0.31
(5)
# OIP3 [mW] .
, IP3
as a function
Figure 7 plots FOM Bnew
of frequency. As some publications
do not specify IP3, fewer data points
are available for generating Figure 7
compared to the previous figures.

Conclusions
In this article, we introduced a new
survey containing data freely available
for use relating to more than 500 LNAs.
We discussed various performance
metrics and suggested a method
of determining FOMs that is arguably more appropriate than existing
methods for comparing LNA design
methods. Of course, there may be
many other ways of using such a survey as well as better ways of identifying trends and FOMs. We eagerly look
forward to seeing whether our initial
effort helps others in their work. As
noted earlier, we would also be more
than happy to correct any errors or
omissions that have inadvertently crept
into the survey.
