Mounting Config. Notes

1. Ground / thermal vias are critical for the proper performance of this

device. Vias should use a .35mm (#80 / .0135”) diameter drill and

have a final plated thru diameter of .25 mm (.010”).

2. Add as much copper as possible to inner and outer layers near the

part to ensure optimal thermal performance.

3. Mounting screws can be added near the part to fasten the board to a

heatsink. Ensure that the ground / thermal via region contacts the

heatsink.

4. Do not put solder mask on the backside of the PC board in the

region where the board contacts the heatsink.

5. RF trace width depends upon the PC board material and

construction.

6. Use 1 oz. Copper minimum.

7. All dimensions are in millimeters (inches). Angles are in degrees.
