Bottom Center Paddles
The bottom center paddles must be electrically grounded for
proper RF performance. Customers should place adequate
thermal vias under the ground paddles for optimum thermal
performance. The Evaluation Board layout (see Figures 3 and 4)
can be used as a guide for RF ground and thermal layout.
