Note: 1. Backside metal paddle is RF and DC ground.
Mounting Recommendation (in mm)
Note: 1. Add as much copper as possible to inner and outer layers
near the part to ensure optimal thermal performance.
2. To ensure reliable operation, device ground paddle-to-ground
pad soldering is critical.
3. Add mounting screws near the part to fasten the board to a
heat sinker. Ensure that the ground / thermal via region contacts the heat sinker.
4. A proper heat dissipation path underneath the area of the
PCB for the mounted device is strictly required for proper
thermal operation. Damage to the device can result from inappropriate heat dissipation.
