MGA-81563
0.1–6 GHz 3 V, 14 dBm Amplifier
Data Sheet
Description
Avago’s MGA-81563 is an economical, easy-to-use GaAs
MMIC amplifier that offers excellent power and low noise
figure for applications from 0.1 to 6 GHz. Packaged in
an ultra-miniature SOT-363 package, it requires half the
board space of a SOT-143 package.
The output of the amplifier is matched to 50Ω (better
than 2.1:1 VSWR) across the entire bandwidth. The input is
partially matched to 50Ω (better than 2.5:1 VSWR) below
4 GHz and fully matched to 50Ω (better than 2:1 VSWR)
above. A simple series inductor can be added to the in-
put to improve the input match below 4 GHz. The ampli-
fier allows a wide dynamic range by offering a 2.7 dB NF
coupled with a +27 dBm Output IP3.
The circuit uses state-of-the-art PHEMT technology
with proven reliability. On-chip bias circuitry allows op-
eration from a single +3 V power supply, while resistive
feedback ensures stability (K>1) over all frequencies and
temperatures.

MGA-81563 Applications Information
Introduction
This high performance GaAs MMIC amplifier was
developed for commercial wireless applications from
100 MHz to 6 GHz.
The MGA-81563 runs on only 3 volts and typically requires
only 42 mA to deliver 14.8 dBm of output power at 1 dB
gain compression.
An innovative internal bias circuit regulates the device’s
internal current to enable the MGA-81563 to operate over
a wide temperature range with a single, positive power
supply of 3 volts. The MGA-81563 will operate with re-
duced performance with voltages as low as 1.5 volts.
The MGA-81563 uses resistive feedback to simultaneously
achieve flat gain over a wide bandwidth and match the in-
put and output impedances to 50Ω. The MGA-81563 is un-
conditionally 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.
With a combination of high linearity (+27 dBm output IP )
3
and low noise figure (3 dB), the MGA-81563 offers out-
standing performance for applications requiring a high
dynamic range, such as receivers operating in dense sig-
nal environments. A wide dynamic range amplifier such as
the MGA-81563 can often be used to relieve the require-
ments of bulky, lossy filters at a receiver’s input.
The 14.8 dBm output power (P1dB) also makes the MGA-
81563 extremely useful for pre-driver, driver and buffer
stages. For transmitter gain stage applications that re-
quire higher output power, the MGA-81563 can provide
50 mW (17 dBm) of saturated output power with a high
power added efficiency of 45%.
Test Circuit
The circuit shown in Figure 10 is used for 100% RF testing
of Noise Figure and Gain. The 3.9 nH inductor at the input
fix-tunes the circuit to 2 GHz. The only purpose of the RFC
at the output is to apply DC bias to the device under test.
Tests in this circuit are used to guarantee the NF and G
test test
parameters shown in the table of Electrical Specifications.

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

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 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 3 non-consecutive process lots of semiconductor
wafers. The data derived from product characterization
tends to be normally distributed, e.g., fits the standard
“bell curve.”
Parameters considered to be the most important to sys-
tem performance are bounded by minimum or maximum
values. For the MGA-81563, these parameters are: Gain
(G ), Noise Figure (NF ), and Device Current (I ). Each of
test test
d
these guaranteed parameters is 100% tested.
Values for most of the parameters in the table of Electrical
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 the Noise and S-parameter tables or
performance curves, the data represents a nominal part
taken from the “center” of the characterization distribu-
tion. Typical values are intended to be used as a basis for
electrical design.
To assist designers in optimizing not only the immediate
circuit using the MGA-81563, but to also optimize and
evaluate trade-offs that affect a complete wireless system,
the standard deviation (V) is provided for many of the
Electrical Specifications parameters (at 25°) in addition
to the mean. The standard deviation is a measure of the
variability about the mean. It will be recalled that a nor-
mal distribution is completely described by the mean and
standard deviation.
