Functional Diagram
General Description
The HMC-APH633 is a two stage GaAs HEMT MMIC
Medium Power Amplifier which operates between
71 and 76 GHz. The HMC-APH633 provides 13 dB
of gain, and an output power of +20 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-APH633 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).
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.
0.127mm (0.005”) Thick Alumina
Thin Film Substrate
Storage: All bare die are placed in either Waffle or Gel based ESD protecFigure 1.
tive 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.
Transients: Suppress instrument and bias supply transients while bias is applied. Use shielded signal and bias
cables to minimize inductive pick-up.
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 may have 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.
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).

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).
