An automatic gain control unit(117) adjusts the recovered degree of the attenuation level of the high-speed RF data signal according to an input control signal. A data signal amplifying unit(119) amplifies a voltage level of an inputted high-speed RF data signal, and outputs the amplified high-speed RF data signal to the signal mixing and dividing unit(111). A reference electric potential generating unit(115) provides a reference electric potential for recovering the high-speed RF data signal and amplifying the input data signal.
