Abstract
Some embodiments discussed relate to a method and apparatus, comprising a power amplifier module, a transceiver module coupled to provide a signal to an input of the power amplifier module. The transceiver module comprising an integrated temperature sensor to sense an instantaneous operating temperature of the transceiver and providing a first sensor output signal dependent upon the operating temperature, and an integrated voltage sensor to sense a transceiver supply voltage and generate a second sensor output signal dependent upon the instantaneous transceiver supply voltage, and a processor configured to receive the first and the second sensor output signals, provide a control signal to the power amplifier module to reduce the output power of the power amplifier responsive to the first and the second sensor output signals.
