General Description
Functional Diagram
The HMC329LM3 is a 26 - 40 GHz surface mount,
passive, double-balanced MMIC mixer in a SMT
leadless chip carrier package. The mixer can be
used as a downconverter or upconverter. Excellent
isolations are provided by on-chip baluns. The chip
requires no external components and no DC bias.
All data is with the non-hermetic, epoxy sealed LM3
package mounted in a 50 Ohm test fixture. Utilizing
the HMC329LM3 eliminates the need for wirebonding, thereby providing a consistent connection
interface for the customer.

devices and PCBs. LM3 devices should remain in their original
packaging until component placement to ensure no contamination or damage to RF, DC & ground contact areas.

Static Sensitivity: Follow ESD precautions to protect against ESD strikes.
General Handling: Handle the LM3 package on the top with a vacuum collet or along the edges with a sharp pair
of bent tweezers. Avoiding damaging the RF, DC, & ground contacts on the package bottom. Do not apply excess
pressure to the top of the lid.
Solder Materials & Temperature Profile: Follow the information contained in the application note. Hand soldering is
not recommended. Conductive epoxy attachment is not recommended.
Solder Paste: Solder paste should be selected based on the user’s experience and be compatible with the metallization
systems used. See the LM3 data sheet Outline drawing for pin & ground contact metallization schemes.
Solder Paste Application: Solder paste is generally applied to the PCB using either a stencil printer or dot placement.
The volume of solder paste will be dependent on PCB and component layout and should be controlled to ensure
consistent mechanical & electrical performance. Excess solder may create unwanted electrical parasitics at high
frequencies.
MIXERS - DBL-BAL - SMT
Follow these precautions to avoid permanent damage:
225
TEMPERATURE ( C)
The HMC LM3 package was designed to be compatible with high
volume surface mount PCB assembly processes. The LM3 package
requires a specific mounting pattern to allow proper mechanical
attachment and to optimize electrical performance at millimeterwave
frequencies. This PCB layout pattern can be found on each LM3
product data sheet. It can also be provided as an electronic drawing
upon request from Hittite Sales & Application Engineering.
Solder Reflow: The soldering process is usually accomplished in a reflow oven but may also use a vapor phase
process. A solder reflow profile is suggested above.
Prior to reflowing product, temperature profiles should be measured using the same mass as the actual assemblies.
The thermocouple should be moved to various positions on the board to account for edge and corner effects and
varying component masses. The final profile should be determined by mounting the thermocouple to the PCB at the
location of the device.
Follow solder paste and oven vendor’s recommendations when developing a solder reflow profile. A standard profile
will have a steady ramp up from room temperature to the pre-heat temperature to avoid damage due to thermal shock.
Allow enough time between reaching pre-heat temperature and reflow for the solvent in the paste to evaporate and the
flux to completely activate. Reflow must then occur prior to the flux being completely driven off. The duration of peak
reflow temperature should not exceed 15 seconds. Packages have been qualified to withstand a peak temperature of
235°C for 15 seconds. Verify that the profile will not expose device to temperatures in excess of 235°C.
Cleaning: A water-based flux wash may be used.
