Description
The MAAM37000 die is a wide-band, low noise,
MMIC amplifier. It includes two integrated gain
stages and employs series inductive feedback to
obtain excellent noise figure and a good 50 Ω, input
and output impedance match over the entire
frequency band. The MAAM37000 operates from a
single +4 V supply.
The MAAM37000 performs well as a low noise
amplifier in receive applications and as a driver or
buffer amplifier where high gain, excellent linearity
and low power consumption are important. Because
of its wide bandwidth, the MAAM37000 can be used
in numerous commercial and government system
applications, such as TVRO, VSAT, missile
guidance, and radar.
The MAAM37000 is
manufactured in-house using a reliable, 0.5-micron,
GaAs MESFET process. This product is 100% RF
tested to ensure compliance to performance
specifications.

Typical Bias Configuration 3,4,5
Rev. V7
Outline Drawing
3. Nominal bias is obtained with on-chip resistors by grounding
pads S1b and S2b.
4. Ground pads S1b and S2c for lower second state current.
5. Optional biasing can be obtained with off-chip resistors bonded
from pads S1a and S2a to ground. Adjusting the bias can
customize the performance to suit special requirements.

Handling Procedures
Bonding
Permanent damage to the MAAM37000 may occur
if the following precautions are not adhered to:
A. Ball or wedge bond with 1.0 mil diameter gold
wire of 3.0 mil x 0.5 mil ribbon. Thermosonic
bonding with a nominal stage temperature of
150°C and a ball bonding force of 40 to 50
grams or wedge bonding force of 18 to 22
grams is recommended. Ultrasonic energy and
time should be adjusted to the minimum levels
necessary to achieve reliable bonds.
B. Bonds should be started on the die and terminated on the package.
C. Bonding pads are 4.0 x 4.0 mils minimum.
A. Cleanliness - The MAAM37000 should be handled in a clean environment. DO NOT attempt
to clean assembly after the MAAM37000 is
installed.
B. Static Sensitivity - All die handling equipment
and personnel should comply with DOD-STD1686 Class I.
C. Transients - Avoid instrument and power supply transients while bias is connected to the
MAAM37000. Use shielded signal and bias
cables to minimize inductive pick-up.
D. General Handling - DO NOT touch the surface
of the die.
It is recommended that the
MAAM37000 die be handled along the long
side with a sharp pair of tweezers.
Mounting
The MAAM37000 is back-metallized with Pd/Ni/Au
(100/1, 000/30,000Å) metallization. It can be diemounted using Au/Sn eutectic preforms or a thermally and electrically conductive epoxy. The attachment surface should be clean and flat.
Eutectic Die Attach:
A. An 80/20 Au/Sn preform is recommended with
a work surface temperature of approximately
255°C and a tool temperature of 265°C. When
hot 95/5 nitrogen/hydrogen gas is applied, solder temperature should be approximately 290°
C.
B. DO NOT expose the MAAM37000 to a temperature greater than 320°C for more than 20
seconds. No more than 3 seconds of scrubbing should be required for attachment.
Epoxy Die Attach:
A. Electrically conductive epoxy is required.
B. Apply a minimum amount of epoxy and place
the MAAM37000 into position. A thin epoxy
fillet should be visible around the perimeter of
the die.
C. Cure epoxy per manufacturer’s recommended
schedule.
