Abstract
A power controllable wireless communication device includes a variable gain amplifier having a gain that can be controlled based on a gain control signal, a reference power generation circuit, which generates first reference power and second reference power differing from the first reference power, a sensor circuit supplied with selectively power of a high frequency signal output from the variable gain amplifier, and the first reference power and the second reference power generated by the reference power generation circuit, and a control circuit which generates the gain control signal based on a sensor output from the sensor circuit. When controlling power, the control circuit generates the gain control signal based on ratios among a first sensor output corresponding to the first reference power, a second sensor output corresponding to the second reference power, and a high frequency sensor output corresponding to the power of the high frequency signal.
