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