General Description
Functional Diagram
The HMC331 is a passive miniature frequency
doubler MMIC. Suppression of undesired fundamental
and higher order harmonics is 50 dB typical with
respect to input signal level. The doubler utilizes the
same GaAs Schottky diode/balun technology found
in Hittite MMIC mixers. It features small size, requires
no DC bias, and adds no measurable additive phase
noise onto the multiplied signal.

Mounting & Bonding Techniques for Millimeterwave GaAs MMICs
The die should be attached directly to the ground plane eutectically or with
conductive epoxy (see HMC general Handling, Mounting, Bonding Note).
0.102mm (0.004”) Thick GaAs MMIC

50 Ohm Microstrip transmission lines on 0.127mm (5 mil) thick alumina thin film
substrates are recommended for bringing RF to and from the chip (Figure 1). If
0.254mm (10 mil) thick alumina thin film substrates must be used, the die should be
raised 0.150mm (6 mils) so that the surface of the die is coplanar with the surface
of the substrate. One way to accomplish this is to attach the 0.102mm (4 mil) thick
die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then
attached to the ground plane (Figure 2).

(0.003”)
RF Ground Plane
Microstrip substrate should be brought as close to the die as possible in order to
minimize ribbon bond length. Typical die-to-substrate spacing is 0.076mm (3 mils).
Gold ribbon of 0.075mm ( 3 mil) width and minimal length <0.31mm ( <12 mils) is
recommended to minimize inductance on RF ports.,

Handling Precautions
Follow these precautions to avoid permanent damage.
0.102mm (0.004”) Thick GaAs MMIC
Storage: All bare die are placed in either Waffle or Gel based ESD protective
containers, and then sealed in an ESD protective bag for shipment. Once the
sealed ESD protective bag has been opened, all die should be stored in a dry
nitrogen environment.

Cleanliness: Handle the chips in a clean environment. DO NOT attempt to clean
the chip using liquid cleaning systems.
Static Sensitivity: Follow ESD precautions to protect against ESD strikes.
RF Ground Plane
Transients: Suppress instrument and bias supply transients while bias is applied.
Use shielded signal and bias cables to minimize inductive pick-up.

Moly Tab
General Handling: Handle the chip along the edges with a vacuum collet or with
a sharp pair of bent tweezers. The surface of the chip has fragile air bridges and
should not be touched with vacuum collet, tweezers, or fingers.

Mounting
The chip is back-metallized and can be die mounted with AuSn eutectic preforms or with electrically conductive epoxy. The mount-
ing surface should be clean and flat.
Eutectic Die Attach: A 80/20 gold tin preform is recommended with a work surface temperature of 255 °C and a tool temperature of
265 °C. When hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290 °C. DO NOT expose the chip to a tem-
perature greater than 320 °C for more than 20 seconds. No more than 3 seconds of scrubbing should be required for attachment.
Epoxy Die Attach: Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fillet is observed around the
perimeter of the chip once it is placed into position. Cure epoxy per the manufacturer’s schedule.
Wire Bonding
RF bonds made with 0.003” x 0.0005” ribbon are recommended. These bonds should be thermosonically bonded with a force of
40 - 60 grams. DC bonds of 0.001” (0.025mm) diameter, thermosonically bonded, are recommended. Ball bonds should be made
with a force of 40 - 50 grams and wedge bonds at 18 - 22 grams. All bonds should be made with a nominal stage temperature of 150
°C. A minimum amount of ultrasonic energy should be applied to achieve reliable bonds. All bonds should be as short as possible,
less than 12 mils (0.31 mm).
