Title:
RADIO COMMUNICATION DEVICE AND METHOD FOR CONTROLLING TRANSMISSION POWER
Document Type and Number:
WIPO Patent Application WO/2014/122718
Kind Code:
A1
Abstract:
In the present invention, a variable-gain amplifier amplifies a baseband signal. A quadrature modulator performs quadrature modulation on 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 a desired transmission power for the high-frequency signal transmitted by the antenna. A controller adjusts a gain of the variable-gain amplifier in accordance with the output of the detector and the transmission power stored in the first nonvolatile memory.
