Abstract
A wireless communication device includes a baseband variable gain amplifier that amplifies a transmission baseband signal, a local variable gain amplifier that amplifies a local signal, a frequency-conversion circuit that mixes the amplified transmission baseband signal and the amplified local signal to carry out a frequency conversion into a transmission high-frequency signal, a first detector that detects a power of the transmission high-frequency signal, and a controller that controls at least one of a gain of the transmission baseband variable gain amplifier and a gain of the local variable gain amplifier on the basis of the detected power of the transmission high-frequency signal so that a power of the transmission high-frequency signal to be detected takes a predetermined value.
