RFIO Stripline
The RFIO pad on the radio module is connected directly to an antenna on the host circuit board, or to an MMCX
or similar RF connector. It is important that this connection be implemented as a 50 ohm stripline. Referring to
Figure 3, the width of this stripline depends on the thickness of the circuit board between the stripline and the

groundplane. For FR-4 type circuit board materials (dielectric constant of 4.7), the width of the stripline is equal to
1.75 times the thickness of the circuit board. Note that other circuit board traces should be spaced away from the
stripline to prevent signal coupling, as shown in Figure 4. The stripline trace should be kept short to minimize its
insertion loss.
