A booster circuit is provided to prevent an inflow of a harmonic signal into a tuner by forming a harmonic signal removal unit at an output terminal thereof. A booster circuit includes a transistor for amplifying an inputted radio frequency signal and a capacitor for outputting the amplified signal to a tuner. The booster further includes a harmonic removal unit(20) for removing a harmonic signal to be outputted from the transistor to the capacitor. The harmonic removal unit is connected in parallel to the capacitor. The harmonic removal unit is composed of a grounding resistor having capacitance of a permissible range for preventing the reduction of the sensitivity of the radio frequency signal. |
