Typical Applications
Features
The HMC264LM3 is ideal for:
Integrated LO Amplifier: -4 dBm Input
• 20 and 30 GHz Microwave Radios
Sub-Harmonically Pumped (x2) LO
• Up and Down Converter for
Point-to-Point Radios

MIXERS - SUB-HARMONIC - SMT
• LMDS and SATCOM
Functional Diagram
General Description
The HMC264LM3 is a 20 - 30 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer with an
integrated LO amplifier in a SMT leadless chip carrier package. The 2LO to RF isolation is an excellent 25 to 35 dB, eliminating the need for additional
filtering. The LO amplifier is a single bias (+3V to +4V)
two stage design with only -4 dBm drive requirement.
All data is with the non-hermetic, epoxy sealed LM3
packaged device mounted in a 50 ohm test fixture.
Utilizing the HMC264LM3 eliminates the need for
wirebonding, thereby providing a consistent connection interface for the customer.

Follow these precautions to avoid permanent damage:

Cleanliness: Observe proper handling procedures to ensure
clean devices and PCBs. LM3 devices should remain in their

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.
Solder Reflow
MIXERS - SUB-HARMONIC - SMT
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.
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.
