RFM92W/93W V3.0
Notes - For +20 dBm restrictions on operation please consult the following section.
- To ensure correct operation at the highest power levels ensure that the current limiter OcpTrim is adjusted to
permit delivery of the requisite supply current.
- If the PA_BOOST pin is not used it may be left floating.
