To maximize RF performance, the host layout should follow these recommendations:
1. The ideal placement of the Cypress BLE module is in a corner of the host board with the antenna located on the edge of the host
board. This placement minimizes the additional recommended keep-out area shown in item 2. Refer to
AN96841
for module
placement best practices.
2. To maximize RF performance, the area immediately around the Cypress BLE module chip antenna should contain an additional
keep-out area, where no grounding or signal traces are contained. The keep-out area applies to all layers of the host board. The
recommended dimensions of the host PCB keep-out area are shown in
Figure 3
(dimensions are in mm).
