ABSTRACT:
A method for temperature compensation of transmit power of a wireless communication device begins by measuring transmit power of the wireless communication device at a first temperature-based biasing condition to produce a first measured transmit power. The method continues by measuring transmit power of the wireless communication device at a second temperature-based biasing condition to produce a second measured transmit power. The method continues by determining ambient temperature of at least a portion of the wireless communication device based on the first and second measured transmit powers and a relationship between the first and second temperature-based biasing conditions. The method continues by compensating transmit power level of the wireless communication device based on the ambient temperature.
