General Description
LE
The HMC1022 is a GaAs pHEMT MMIC Distributed Power Amplifier which operates between DC
and 48 GHz. The amplifier provides 12 dB of gain,
32 dBm output IP3 and +22 dBm of output power at
1 dB gain compression while requiring 150 mA from
a +10 V supply. The HMC1022 exhibits a slightly
positive gain slope from 10 to 35 GHz, making
it ideal for EW, ECM, Radar and test equipment
applications. The HMC1022 amplifier I/Os are
internally matched to 50 Ohms facilitating integration into Multi-Chip-Modules (MCMs). All data is
taken with the chip connected via two 0.025 mm
(1 mil) wire bonds of minimal length 0.31 mm (12 mils).

The die should be attached directly to the ground plane eutectically or with
conductive epoxy (see HMC general Handling, Mounting, Bonding Note).
Wire Bond

TE
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).
0.102mm (0.004”) Thick GaAs MMIC
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).
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:

Mounting & Bonding Techniques for Millimeterwave GaAs MMICs
Mounting
O
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 two 1 mil wires 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
