PCB Mounting Pattern

NOTES:

1. All dimensions are in millimeters. Angles are in degrees.

2. Use 1 oz. copper minimum for top and bottom layer metal.

3. Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation.

4. Do not remove or minimize via hole structure in the PCB. Thermal and RF grounding is critical.

5. We recommend a 0.35mm (#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25 mm

(0.10”).

6. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
