General Description

The HMC258LM3 is a 14 - 20 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer with
an integrated LO amplifi er in a SMT leadless chip
carrier package. The 2LO to RF isolation is an
excellent 40 dB, eliminating the need for addi­tional fi ltering. The LO amplifi er is a single bias
(+5V) two stage design with only 0 dBm drive
requirement. All data is with the non-hermetic,
epoxy sealed LM3 packaged device mounted in
a 50 ohm test fi xture. Utilizing the HMC258LM3
eliminates the need for wirebonding, thereby pro­viding a consistent connection interface for the
customer.

The grounded Co-Planar Wave Guide (G-CPW) PCB input/output transitions allow use of Ground-Signal­Ground (GSG) probes for testing. Suggested probe pitch is 400mm (16 mils). Alternatively, the board can
be mounted in a metal housing with 2.4 mm coaxial connectors.

HMC258LM3 Recommended SMT Attachment Technique

Preparation & Handling of the LM3 Millimeterwave Package for Surface Mounting

The HMC LM3 package was designed to be compatible with high
volume surface mount PCB assembly processes. The LM3 package
requires a specifi c mounting pattern to allow proper mechanical attach-
ment 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.

Follow these precautions to avoid permanent damage:

Cleanliness: Observe proper handling procedures to ensure clean
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.

MIXERS - SMT

Static Sensitivity: Follow ESD precautions to protect against ESD
strikes ( see catalog page 8 - 2 ).

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 Profi le: 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 Refl ow

The soldering process is usually accomplished in a refl ow oven but may also use a vapor phase process. A solder refl ow profi le is
suggested above.

Prior to refl owing product, temperature profi les 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 fi nal
profi le 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 refl ow profi le. A standard profi le 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 refl ow for the solvent in the paste to evaporate and the fl ux to completely activate. Refl ow must
then occur prior to the fl ux being completely driven off. The duration of peak refl ow temperature should not exceed 15 seconds. Pack-
ages have been qualifi ed to withstand a peak temperature of 235°C for 15 seconds. Verify that the profi le will not expose device to
temperatures in excess of 235°C.

Cleaning

A water-based fl ux wash may be used.
