Note: Maximum RF TX power of 28 dBm is calibrated and programmed in production per module, this is the same for
revision 1.0 and 2.0 hardware. However, Half power (26dBm)=eeprom value 0A, Quarter power (23dBm)=eeprom
value 07 and Low power (10dBm)=eeprom value 01 settings gives a lower RF TX power on AC4790-1000M
revision 2.0 hardware. Customer must set the appropriate EEPROM hex value on AC4790-1000M revision 2.0
hardware to get half power (26dBm), quarter power (23dBm), and low power (10dBm) modes.
