(Recommended Footprint)

Note: 1. The number and size of ground via holes in

a circuit board is critical for thermal RF

grounding considerations.

2. We recommend that the ground via holes be

placed on the bottom of all ground pins for

better RF and thermal performance, as

shown in the drawing at the left side.
