Mounting and Thermal Considerations
It is very important that adequate heat sinking be provided to minimize the device junction temperature. The following items
should be implemented to maximize MTTF and RF performance.
1. Multiple solder-filled vias are required directly below the ground tab (pin 4). [CRITICAL]
2. Incorporate a large ground pad area with multiple plated-through vias around pin 4 of the device. [CRITICAL]
3. Use two point board seating to lower the thermal resistance between the PCB and mounting plate. Place machine screws as
close to the ground tab (pin 4) as possible. [CRITICAL]
4. Use 2 ounce copper to improve the PCB’s heat spreading capability. [RECOMMENDED]
