Typical Applications
The HMC650 through HMC658 are ideal for:
• Fiber Optics
• Microwave Radio
• Military & Space Hybrids
• Test & Measurement
• Scientific Instruments
• RF / Microwave Circuit Prototyping
The HMC650 / 651 / 652 / 653 / 654 / 655 / 656 / 657
/ 658 are a line of wideband fixed value 50 Ohm mat-
ched attenuator chips which offer relative attenuation
levels of 0, 2, 3, 4, 6, 10, 15 and 20 dB. These passive
though-lines and attenuators are ideal for microstrip,
hybrid, and multi-chip module applications where
extremely flat attenuation, and excellent VSWR vs.
frequency are required.
These wideband attenuators feature low inductance
on-chip vias, and require no additional ground
connections. The HMC650 through HMC658 are
backside metallized with gold, and are suitable for
eutectic or epoxy die attach. Each of the 9 products
can be purchased individually by their respective
part number or in a set of 10 each in the HMC-DK006
Fixed Attenuator Chip Designers Kit.

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).
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 accom-
plish 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).
Microstrip substrates should brought 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 protec-
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 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.
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 manufacturers schedule.
Wire Bonding
Ball or wedge bond with 0.025mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with a nominal stage
temperature of 150 °C and a ball bonding force of 40 to 50 grams or wedge bonding force of 18 to 22 grams is recom-
mended. Use the minimum level of ultrasonic energy to achieve reliable wirebonds. Wirebonds should be started on
the chip and terminated on the package or substrate. All bonds should be as short as possible <0.31mm (12 mils).
