Transmitter Power decreases as temperatures rise and increases as
temperatures fall. Use the Output Power Coefficient to calculate increased or
decreased power output for your operating environment. For example, the
typical power output at 25
temperatures fall. Use the Output Power Coefficient to calculate increased or
decreased power output for your 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).
output power (4 x -0.15 dBm + -16.4 = -17.0).
