Claim:
1. A power controllable wireless communication device comprising: a variable gain amplifier having a gain that can be controlled based on a gain control signal; a reference power generation circuit configured to generate 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 configured to generate the gain control signal based on a sensor output from the sensor circuit, wherein 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, and a second sensor output corresponding to the second reference power, which are output from the sensor circuit, and a high frequency sensor output corresponding to the power of the high frequency signal.
