5. DESIGN GUIDE TO AVOID RF INTERFERENCE
When RF module put on an application board(mother board), to minimize the RF signal
interference, the best way is to define an isolation area. This area should have no any trace or
grounding pad. Here are some layout suggestions for mother board.
Suggestion 1: Place RF board aside mother board. (Let antenna part outside mother board is
better) Make sure no trace and grounding pad under the must isolate area. Please see the drawing
as below.
