Backside metal paddle is RF and DC ground. . Mounting Recommendation(in 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 for better RF and thermal performance, as shown in the drawing at the left side.
