General Description
The HMC441LM1 is a broadband 7 to 15.5 GHz GaAs
PHEMT MMIC Medium Power Amplifier in an SMT
leadless chip carrier package. The amplifier provides
15 dB of gain, 21.5 dBm of saturated power at 27%
PAE from a +5V supply voltage. An optional gate bias is
provided to allow adjustment of gain, RF output power,
and DC power dissipation. This 50 Ohm matched
amplifier does not require any external components
making it an ideal linear gain block or driver for HMC
SMT mixers.

Recommended SMT Attachment Technique
Preparation & Handling of the LM1 Microwave Package for Surface Mounting
Cleanliness: Observe proper handling procedures to ensure clean devices
and PCBs. LM1 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 LM1 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 LM1 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: 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.

The HMC LM1 package was designed to be compatible with high volume
surface mount PCB assembly processes. The LM1 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 LM1 product data sheet. It can also
be provided as an electronic drawing upon request from Hittite Sales &
Application Engineering.
