Variable Documentation

const float fPowerFactors[5][6] [static]
Initial value:
{ 
  {-2.11,25.66,-2.11,25.66,-2.00,31.28},   
  {-2.04,23.45,-2.04,23.45,-1.95,27.66},   
  {-3.48,38.45,-1.89,27.66,-1.92,30.23},   
  {-3.27,35.43,-1.80,26.31,-1.89,29.61},   
  {-4.18,50.66,-1.80,30.04,-1.86,32.22},   
}

These values are used to interpolate the power curves.

Interpolation curves are linear in the following 3 regions:

  • reg value: 1 to 13 (up region)
  • reg value: 13 to 40 (mid region)
  • reg value: 41 to 90 (low region) power_reg = m*power_dBm + q For each band the order is: {m-up, q-up, m-mid, q-mid, m-low, q-low}.
    Note:
    The power interpolation curves have been extracted by measurements done on the divisional evaluation boards.

It represents the available channel bandwidth times 10 for 26 Mhz xtal.

Note:
The channel bandwidth for others xtal frequencies can be computed since this table multiplying the current table by a factor xtal_frequency/26e6.
