PRELIMINARY
CYSBSYS-RP01
Recommended Host PCB Layout
Figure 5 provides details that can be used for the recommended host PCB layout pattern for CYSBSYS-RP01. Dimensions are in
millimeters unless otherwise noted. Pad length of 1.02 mm as shown in
Figure 5 is the minimum recommended host pad length. All
dimensions are referenced to the center of the solder pad.
To maximize performance, the host layout should follow these recommendations:
1. The ideal placement of the CYSBSYS-RP01 board is in a corner of the host board with the antenna located outside the edge of
the host board. This placement minimizes the additional recommended keep out area stated in item 3.
2. To maximize RF performance, the area immediately around the system antenna should contain a keep out area, where no grounding
or signal traces are contained. This 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 5.
3. If fanout of traces are done under the board, care should be taken to fill the used area under the board with copper plane to avoid
any unbalanced surface that may lead to an assembly issue.
4. No metal should be located beneath or above the antenna area. Only bare PCB material should be located beneath the antenna
area.
