NOTE: 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
°
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).
