Functional Diagram
General Description
The HMC553 is a passive double balanced mixer
that can be used as an upconverter or downconverter
between 7 and 14 GHz. The miniature monolithic
mixer is fabricated in a GaAs MESFET process, and
requires no external components or matching circuitry. The HMC553 operates with LO drive levels as
low as +9 dBm and provides excellent LO to RF and
LO to IF isolation due to optimized balun structures.
Measurements were made with the chip mounted
into in a 50 ohm test fixture and includes the parasitic effects of wire bond assembly. Connections were
made with a 1 mil wire bond with minimal length (<12
mil).

IF
This pad is DC coupled. For applications not requiring operation to DC, this port should be DC blocked externally using
a series capacitor whose value has been chosen to pass the
necessary IF frequency range. For operation to DC, this pin
must not source or sink more than 2 mA of current or part
non-function and possible part failure will result.

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).

3 mil Ribbon Bond
0.076mm
(0.003”)
RF Ground Plane
Microstrip substrates 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 0.075 mm (3 mil) width and minimal length <0.31 mm (<12 mils) is
recommended to minimize inductance on RF, LO & IF ports.

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: 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.

Figure 2.
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
Ball or wedge bond with 0.025 mm (1 mil) diameter pure gold wire is recommended. 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 recommended. 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 <0.31 mm (12 mils).
