Mounting Recommendation
(Unit: mm)
Note: 1. The number and size of ground via holes in a circuit board
is critical for thermal and RF grounding considerations.
2. We recommend that the ground via holes be placed on the
bottom of the lead pin 2 and exposed pad of the device for
better RF and thermal performance, as shown in the drawing at the left side.
