Parameters considered to be the
most important to system perfor-
mance are bounded by minimum
or maximum values. For the
MGA-71543, these parameters are:
V
IL
parameters is 100% tested as part
of the normal manufacturing and
test process.
Values for most of the parameters
in the table of Electrical Specifica-
tions that are described by typical
data are the mathematical mean
(µ), of the normal distribution
taken from the characterization
data. For parameters where
measurements or mathematical
averaging may not be practical,
such as S-parameters or Noise
parameters and the performance
curves, the data represents a
nominal part taken from the
center of the characterization
distribution. Typical values are
intended to be used as a basis for
electrical design.

To assist designers in optimizing
not only the immediate amplifier
circuit using the MGA-71543, but
to also evaluate and optimize
tradeoffs that affect a complete
wireless system, the standard
deviation (σ) is provided for
many of the Electrical Specifica-
tion parameters (at 25°C). The
standard deviation is a measure of
the variability about the mean. It
will be recalled that a normal
distribution is completely de-
scribed by the mean and standard
deviation.
Standard statistics tables or
calculations provide the probabil-
ity of a parameter falling between
any two values, usually symmetri-
cally located about the mean.
Referring to Figure 15 for
example, the probability of a
parameter being between ±1σ is
68.3%; between ±2σ is 95.4%; and
between ±3σ is 99.7%.
Phase Reference Planes
The positions of the reference
plane used to specify S-parameters
and Noise Parameters for the
MGA-71543 are shown in
Figure 16. As seen in the illustra-
tion, the reference planes are
located at the point where the
package leads contact the test
circuit.
