High Signal Performance:
Measured in a single shunt diode (die) configuration attached directly to the gold plated RF ground of a 50 Ω,
SMA connectorized, test fixture using 2 mil thick conductive silver epoxy . Chip anode contact is thermo-compression wire bonded using a
1 mil. diameter gold wire onto a 7.2 mil thick Rogers 5880 Duroid microstrip trace. A shunt coil provides the DC return.

Measured with a single shunt diode (die) attached directly to the gold plated RF housing ground with 2 mil thick
conductive silver epoxy in a 50 Ω, SMA, connectorized test fixture. Chip anode contact is thermo-compression
wire bonded using a 1 mil. diameter gold wire onto a 7.2 mil thick Rogers 5880 Duroid microstrip trace. A shunt
coil provides the DC return.
Maximum CW Incident Power:
Measured in a 50 Ω, SMA, connectorized housing @ 4 GHz utilizing a TWT
amplifier and the same single diode assembly configuration as stated above.
Die Handling and Mounting Information
Handling:
All semiconductor chips should be handled with care in order to avoid damage or contamination from
particulates, salts, and skin oils. For individual die, the use of plastic tipped tweezers or vacuum pick up tools is
strongly recommended. Bulk handling should ensure that abrasion and mechanical shock are minimized.
Die Attach:
The die have Ti-Pt-Au back and anode metal, with a final gold thickness of 1.0 µm. Die can be
mounted with a gold-tin, eutectic solder perform or conductive silver epoxy. The metal RF and D.C. ground plane
mounting surface must be free of contamination and should have a surface flatness or < ±2 mils.
Eutectic Die Attachment Using Hot Gas Die Bonder:
An 80/20, gold / tin eutectic solder perform is
recommended with a work surface temperature of 255°C and a tool tip temperature of 220°C. When the hot
gas is applied, the temperature at the tool tip should be approximately 290°C. The chip should not be
exposed to a temperatures in excess of 320°C for more than 10 seconds.
Eutectic Die Attachment Using Reflow Oven:
Refer to
Application Note M538
“Surface Mounting
Instructions”.
Epoxy Die Attachment:
A thin, controlled amount of electrically conductive silver epoxy should be applied,
approximately 1-2 mils thick to minimize ohmic and thermal resistances. A small epoxy fillet should be visible
around the outer perimeter of the chip after placement to ensure full area coverage. Cure the conductive
silver epoxy per the manufacturer’s schedule, typically 150˚C for 1 hour.
Wire Bonding:
The chip’s top contact (anode) metallization layer is comprised of Ti/Pt/Au with a final gold
thickness of 1.0 µm. Thermo-compression wedge bonding using a 0.7 or 1.0 mil diameter gold wire is
recommended. The heat stage temperature should be set to approximately 200°C with a tool tip temperature of
125˚C and a force of 18 to 40 grams. Use of ultrasonic energy is not advised but if necessary should be adjusted
to the minimum setting required to achieve a good bond. Excessive energy or force applied to the top contact will
cause the metallization to dislodge and lift off. Automatic ball bonding may also be used.
See
Application Note M541
“Bonding and Handling Procedures for Chip Diode Devices” for more detailed
handling and assembly information.
