Abstract
A wireless communication circuit includes: an antenna; a transmitter circuit having an output amplifier outputting a transmission signal to the antenna; a receiver circuit having an LNA into which a reception signal from the antenna is input; and a matching circuit provided between the antenna and the input of the LNA. The LNA has a MOS input transistor receiving at its gate the reception signal from the antenna via the matching circuit, and includes a variable capacitance provided between the gate and source of the input transistor, the capacitance value of the variable capacitance being changed between the transmission time and the reception time.
