Team,
I see that the reference design for the CC3100 MOD is a 2 layer board, and that for FCC cert, antenna layout needs to be duplicated. I am using the CC3100 on a 4 layer board. Do we have a reference design for the CC3100MOD for a 4 layer board or similar?
Thanks,
Sean
For the antenna, this was used as my reference from the CC3100MODBOOST design:
I've rescaled the W and S parameters per the datasheet for a 10mil L1-L2 spacing; does anything else need to be modified for the area area the chip antenna (the blue circled region)? Do these dimensions stay the same?
The current design uses W=20mil, S=18mil, H=10mil
The number of layers on the PCB will not affect the certification transfer. you can follow the guidelines from the CC3100MODBOOST board and just change the width of the microstrip according to your stackup. this can be calculated using standard tools like Txline
The dimensions around the chip antenna shall remain the same.
