The mixer is fabricated in a GaAs MESFET process, and can be used as a downconverter or upconverter. The wide operating bandwidth allows this device to be used across multiple radio bands with a common platform. Excellent isolations are provided by on-chip baluns. The HMC560LM3 requires no external components and no DC bias. All data is with the nonhermetic, epoxy sealed LM3 package mounted in a 50 Ohm test fixture. Utilizing the HMC560LM3 eliminates the need for wire bonding, thereby providing a consistent connection interface for the customer, and allowing the use of surface mount manufacturing techniques.

LM3 devices should remain in their original packaging until component placement to ensure no contamination or damage to RF, DC & ground contact areas. 8 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 metalization systems used. See the LM3 data sheet Outline drawing for pin & ground contact metalization 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 235C for 15 seconds. Verify that the profile will not expose device to temperatures in excess of 235C. Mixers - SINGLE & DOUBLE BALANCED - 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 millimeter wave 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. Cleaning: A water-based flux wash may be used.
