摘要：
A system for determining an amount of power supplied from a power amplifier may include a power amplification circuit having a characteristic thermal resistance, a first temperature sensor for sensing a first temperature associated with the power amplification circuit when the power amplification circuit is receiving power from the power source, a second temperature sensor for sensing a second temperature associated with an environment occupied by the power amplification circuit, and a processor coupled with the first temperature sensor and the second temperature sensor for determining an amount of power dissipation utilizing (A) a temperature difference determined utilizing the first temperature and the second temperature and (B) the characteristic thermal resistance of the power amplification circuit.
