摘要 |
A portable multi-band communication device has a power amplifier, a battery for supplying power to the power amplifier, and a controller, which controls an output power level of the communication device by generating a digital control signal for the power amplifier. The controller monitors the digital control signal and in response determines a consumption of electric energy from the battery. |
