M/A-COM’s MA46H146 is a gallium arsenide flip
chip multiplier varactor These devices are facilitated
on MOVPE epitaxial wafers using a process de-
signed for high device uniformity and extremely low
parasitics. The MA46H146 diodes are fully pas-
sivated with silicon nitride and have an additional
polymide layer for scratch protection. The protective
coatings prevent damage to the junction during
automated or manual handling. The flip chip con-
figuration is suitable for pick and place insertion.

Applications
Handling Procedures
These GaAs Flip Chip devices are suited for milli-
meter wave frequency tunable filters, where ex-
tremely low parastics are required to maintain rea-
sonable Q. In addition, this product can be used in
multiplier circuits, for 2X and 3X output frequencies
in the millimeter wave frequency bands.
The following precautions should damaging GaAs
Flip-Chips:
Cleanliness
These chips should be handled in a clean environ-
ment. Do not attempt to clean die after installation.
Assembly Requirements using
Electrically Conductive Ag Epoxy
Static Voltage Sensitivity
These chips are designed to be inserted onto hard
or soft substrates with the junction side down. They
must be mounted with Electrically Conductive Ag
epoxy. Solders are not recommended due to Tung-
sten metallization beneath the gold contacts. The
die can also be assembled with the junction side
up, and wire or ribbon bonds made from the bond
pads to the circuit trace. Circuit can be preheated
to 125 – 150 °C. Use a controlled amount of con-
ductive epoxy for each bond pad. Finished, uniform
silver epoxy thickness should be between 1 – 2
mils. Cure epoxy per manufacturer’s schedule. For
extended cure times, temperatures must be below
200 °C.
Varactor diodes are ESD sensitive and can be
damaged by static electricity. Proper ESD tech-
niques and precautions should be followed when
handling these devices.
General Handling
The protective polymer coating on the active areas
of these devices provides scratch protection, par-
ticularly for the metal Airbridge which contacts the
anode. Dice can be handled with tweezers or vac-
uum pickups and are suitable for use with auto-
matic pick-and-place equipment.
