Abstract: A balun converts a single-ended radio-frequency signal into differential signals. A differential matching circuit outputs a maximum-level positive-phase output signal at a lower or higher frequency than the center frequency and outputs a maximum-level reverse-phase output signal at a higher or lower frequency than the center frequency. An amplification circuit amplifies a positive-phase output signal and a reverse-phase output signal of the differential matching circuit. A mixing circuit converts the positive-phase output signal and the reverse-phase output signal that are output from the amplification circuit into intermediate-frequency signals using locally generated signals.
