Abstract:
1. A transmitting power level controller of a communication system, the communication system comprising a radio-frequency (RF) unit for generating a communication signal and a power amplifier (PA) for amplifying the communication signal to generate a transmitting signal, the transmitting power level controller comprising: a temperature sensor, for sensing temperature of at least one of the RF unit and the PA to generate a detected temperature signal; a power detector, for detecting a transmitting power of the transmit signal to generate a detected power signal; and an automatic level controller, coupled to the temperature sensor and the power detector, for adjusting the transmitting power of the transmitting signal according to the detected power signal when a maximal transmitting power is in a predetermined range, and adjusting the transmitting power according to the detected temperature signal when the maximal transmitting power is not in the predetermined range.
