Regarding CEPT ERC recommendation 70-03 and ETSI regulation EN 300220 both of the following
figures show full compliance in case of ASK and FSK modulation spectrum. Data signal is a
Manchester encoded PRBS9 (Pseudo Random Binary Sequence), RF output power is +9dBm at a
supply voltage of 3V. With these settings ASK allows a maximum data rate of 25kBaud, in FSK case
40kBaud are possible. See also Section 4.1.4
