2.2. Recommended Layout of Solder Pad Graphs are all in Top View, Unit in mm.
2.3. RF Layout Suggestion (aka Keep-Out Area) Please follow below instruction to have better wireless performance. Make sure to keep the “No-Ground-Pad” as wider as you can when there is not enough space in your design. No Ground Pad should be included in the corresponding position of the antenna in EACH LAYER. Place the module towards the edge of PCB to have better performance than placing it on the center. Welcome to send us your layout in PDF for review at service@raytac.
