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. [CRITICAL]
5. Thermal transfer paste should be used between
the PCB and the mounting plate to improve heat
spreading capability. [RECOMMENDED]
Caution: ESD sensitive
Appropriate precautions in handling, packaging and
testing devices must be observed.
