General Description
The HMC-AUH317 is a high dynamic range, three
stage GaAs HEMT MMIC Medium Power Amplifier
which operates between 81 and 86 GHz. The HMCAUH317 provides 22 dB of gain, and an output power
of +17.5 dBm at 1 dB compression from a +4V supply
voltage. All bond pads and the die backside are Ti/Au
metallized and the amplifier device is fully passivated
for reliable operation. The HMC-AUH317 GaAs
HEMT MMIC Medium Power Amplifier is compatible
with conventional die attach methods, as well as
thermocompression and thermosonic wire bonding,
making it ideal for MCM and hybrid microcircuit
applications. All data shown herein is measured with
the chip in a 50 Ohm environment and contacted with
RF probes.

Mounting & Bonding Techniques for Millimeterwave GaAs MMICs
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).

RF Ground Plane
Microstrip substrates should be placed as close to the die as possible in
order to minimize bond wire length. Typical die-to-substrate spacing is
0.076mm to 0.152 mm (3 to 6 mils).

Handling Precautions
Follow these precautions to avoid permanent damage.
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:
strikes.

Transients: Suppress instrument and bias supply transients while bias is

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 mounting 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 temperature greater than 320 °C for more than 20 seconds. No more than 3 seconds of
scrubbing should be required for attachment.
LINEAR & POWER AMPLIFIERS - CHIP
The die should be attached directly to the ground plane eutectically or with
conductive epoxy (see HMC general Handling, Mounting, Bonding Note).
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” (0.025 mm) 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).
