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 (-0.07 dB) by four and add the result to the typical output power (4°C x -0.07 dB/°C) + (-16.4dBm) = -16.7).
