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.
