CHEMATIC
:
75µm nominal gap on
each side
Input and output thin film
substrates with 50Ω microstrip
transmission lines. Substrate
thickness 250µm or thinner is
recommended.
25µm dia. Au wire (x2) on
input and output ports, less
than 1000µm length each
Note: The supply de-coupling
capacitor (150 pF recommended
value) should be placed as close
to the MMIC as practical.

NSTRUCTIONS
:
GaAs devices are fragile and should be
handled with great care. Specially designed
collets should be used where possible.
The back of the die is metallised and the
recommended mounting method is by the use
of
conductive
epoxy
following
the
manufacturer’s
recommended
curing
temperature.
For eutectic 80/20 gold/tin
solder, use a stage temperature of 280-300°C
for a maximum time of 60s. Use forming gas
(90%N2, 10% H2) for best results.
Recommended lead bond technique is
thermocompression wedge bonding with 25µm
diameter wire. The bond tool force shall be
35-38g. Bonding stage temperature shall be
230-240°C, heated tool (150-160°C) is
recommended.
Ultrasonic bonding is not
recommended.
should be observed at all stages of storage,
handling, assembly, and testing.
These
devices should be treated as Class 0 (0-250 V)
as defined in JEDEC Standard No. 22-A114.
Further information on ESD control measures
can be found in MIL-STD-1686 and MIL-
HDBK-263.
