Transmitter Power decreases as temperatures rise and increases as
temperatures fall. Use the Output Power Coefficient to calculate increased
or decreased power output for the operating environment. For example,
the typical power output at 25
°
C is -16.4 dBm. For a 4
°
C temperature
increase, multiply the typical coefficient (-0.15 dBm) by four and add the
result to typical output power (4 x -0.15 dBm + -16.4 = -17.0).
