Figure 16: Reference Design for RF
BC95 provides an RF antenna pad for antenna connection. There is one grounding pad on the both sides
of the antenna pad in order to give a better grounding. Besides, a π-type match circuit is suggested to be
used to adjust the RF performance, and it is better to keep match circuit close to RF_ANT port of the
module.
