Abstract
A variable gain amplifier amplifies a baseband signal. A quadrature modulator quadrature-modulates the amplified baseband signal to generate a high-frequency signal. A power amplifier amplifies the generated high-frequency signal. An antenna transmits the amplified high-frequency signal. A detector detects the amplified high-frequency signal. A first nonvolatile memory stores the desired transmission power of the high-frequency signal to be transmitted from the antenna. A controller adjusts the gain of the variable gain amplifier depending on the output of the detector and the transmission power stored in the first nonvolatile memory.
