2.2.2.2 Routing Example
Interface to RF Connector
Figure 17 shows a sample connection of a module‘s antenna pad at the bottom layer of the
module PCB with an application PCB‘s coaxial antenna connector. Line impedance depends
on line width, but also on other PCB characteristics like dielectric, height and layer gap. The
sample stripline width of 0.33mm is recommended for an application with a PCB layer stack
resembling the one of the PLS63-W evaluation board shown in Figure 18. For different layer
stacks the stripline width will have to be adapted accordingly.
