Hello,


I want to know about routing of BCM20737S, I have read on datasheet this IC need keepout area around it. There are four sites of keepout area, i have some components and i want to place it on "side B" after keepout area can i do it. Since my pcb is very small i have moved ground L shaped plane to inner layer. Can you tell me the exact location of antenna in the IC? Thanks

Hello Muhammad,

The keep out area suggestions are to obtain the maximum antenna range.

Any deviation from this layout will reduce the range.

We can't know all use cases and ranges for our customers designs but can only offer guidance

The approximate location of the 37S antenna is marked in RED;

Good luck in your design,
