How is 20dBm possible on the Hope radios?
« on: October 07, 2016, 12:16:34 AM »
If the RFIO is shared the maximum output is 14dBm whereas if the RFIO are split into separate antennae the maximum is 20dBm.
So how are people reaching 20dBm ? Is this purely setting the output to 20dBm in software?

See page 77 of the DS for the reference design used on RFM69.

OK, nothing like the SX172/X series.

Again, maybe it would be helpful to define what you are asking about. Ie "How is 20dBm possible in SXxxxx / RFMxx". Can you perhaps update the title? Thanks.
