Hints and Troubleshooting
Oscillation
Unconditional stability of the MGA-83563 is dependent
on having good grounding. Inadequate device ground-
ing or poor PCB layout techniques could cause the device
to be potentially unstable. In a multistage RFIC such as
the MGA-83563, feedback through bias lines supplying
voltage to both stages can lead to oscillation. It is im-
portant to well bypass the connections to bias supply to
ensure stable operation.
Statistical Parameters
Several categories of parameters appear within this data
sheet. Parameters may be described with values that are
either “minimum or maximum, ” “typical, ” or “standard de-
viations. ”
The values for parameters are based on comprehensive
product characterization data, in which automated mea-
surements are made on of a minimum of 500 parts taken
from three non-consecutive process lots of semiconduc-
tor wafers. The data derived from product characteriza-
tion tends to be normally distributed, e.g., fits the stan-
dard bell curve.
Parameters considered to be the most important to system
performance are bounded by minimum or maximum
values. For the MGA-83563, these parameters are: Saturat-

Values for most of the parameters in the table of Electri-
cal Specifications that are described by typical data are
the mathematical mean (P), 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 Param-
eters and the performance curves, the data represents a
nominal part taken from the center of the characteriza-
tion distribution. Typical values are intended to be used
as a basis for electrical design.
To assist designers in optimizing not only the immedi-
ate amplifier circuit using the MGA-83563, but to also
evaluate and optimize trade-offs that affect a complete
wireless system, the standard deviation (V) is provided
for many of the Electrical Specifications parameters (at
25°C) in addition to the mean. The standard deviation is
a measure of the variability about the mean. It will be re-
called that a normal distribution is completely described
by the mean and standard deviation.
Standard statistics tables or calculations provide the
probability of a parameter falling between any two
values, usually symmetrically located about the mean.
Referring to Figure 42 for example, the probability of a
parameter being between ±1V is 68.3%; between ±2V is
95.4%; and between ±3V is 99.7%.

Phase Reference Planes
The positions of the reference planes used to specify S-
parameters and Noise Parameters for the MGA-83563 are
shown in Figure 43. As seen in the illustration, the refer-
ence planes are located at the point where the package
leads contact the test circuit.
