MGA-82563 Applications
Information
Introduction
This medium power GaAs MMIC
amplifier was developed for
commercial wireless applications
from 100 MHz to 6 GHz. The
MGA-82563 runs on only 3 volts
and typically requires only 84 mA
to deliver over 17 dBm of output
power at 1 dB gain compression.
The 17.3 dBm output power
(P1␣ dB ) makes the MGA-82563
extremely useful for pre-driver
and driver stages in transmit
cascades or for final output stages
in lower power systems. For
transmitter gain stage applications
that require even higher output
power, the MGA-82563 can
provide 100 mW (20 dBm) of
saturated output power with a
power added efficiency approach-
ing 50%. The low cost of the
MGA-82563 makes it feasible to
power combine two (or more)
devices for even higher output
power amplifiers.
The MGA-82563 offers an excel-
lent combination of high linearity
(+31 dBm output IP3) and very
low noise figure (2.2 dB) for
applications requiring a very high
dynamic range.
The MGA-82563 uses resistive
feedback to simultaneously
achieve flat gain over a wide
bandwidth and to match the input
and output impedances to 50 Ω.
The MGA-82563 is also uncondi-
tionally stable (K>1) over its
entire frequency range, making it
both very easy to use and yielding
consistent performance in the
manufacture of high volume
wireless products.
An innovative internal bias circuit
regulates the device’s internal
current to enable the MGA-82563
to operate over a wide tempera-
ture range with a single, positive
power supply of 3 volts. The
MGA-82563 will operate with
reduced power and gain with a
bias supply as low as 1.5 volts.
Test Circuit
The circuit shown in Figure 10 is
used for 100% RF testing of Gain
and Noise Figure. The test circuit
is merely a 50 Ω input/output PC
board with a RFC at the output to
apply DC bias to the device under
test. Tests in this circuit are used
to guarantee the NFtest and Gtest
parameters shown in the table of
Electrical Specifications.
Specifications and
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 deviations.”
The values for parameters are
based on comprehensive product
characterization data, in which
automated measurements are
made on of a minimum of
500␣ parts taken from 3 non-
consecutive process lots of
semiconductor wafers. The data
derived from product character-
ization tends to be normally
distributed, e.g., fits the standard
“bell curve.”

Phase Reference Planes
The positions of the reference
planes used to specify the
S-Parameters and Noise Param-
eters for this device are shown in
Figure 11. As seen in the illustra-
tion, the reference planes are
located at the point where the
package leads contact the test
circuit.

Parameters considered to be the
most important to system perfor-
mance are bounded by minimum
or maximum values. For the
MGA-82563, these parameters are:
Gain (Gtest), Noise Figure (NFtest),
and Device Current (Id). Each of
these guaranteed parameters is
100% tested.
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 distribu-
tion taken from the characteriza-
tion data. For parameters where
measurements or mathematical
averaging may not be practical,
such as the Noise and S-parameter
tables or 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.
