5.4.13
FCC Part 15.247 allows for systems employing digital
modulation techniques to transmit up to 1 W, provided
that the 6 dB bandwidth of the signal is at least 500 kHz
and that the power spectral density does not exceed
8 dBm in any 3 kHz bandwidth.

Preliminary
The MRF89XA can meet these constraints while
transmitting at the maximum output power of the
device, typically 10 dBm. The built-in whitening
process details are described in Section 3.11.4.2
“Data Whitening”.
