The invention relates to a semiconductor device and an adjustment method of a filter circuit. The filter circuit is operable to pass a desired signal component of a high-frequency signal inputted and operable to attenuate a harmonic component of an integral multiple of the desired signal, wherein The filter circuit is a notch filter which includes a first inductor and a second inductor coupled in series to a signal line transmitting the high-frequency signal, a first variable capacitor coupled between a power supply line and a node of the first inductor and the second inductor, and a second variable capacitor coupled between the signal line and the power supply line. The frequency of the desired signal component is adjusted by capacitance values of the first variable capacitor and the second variable capacitor, and the frequency of the third harmonic component is adjusted by a capacitance value of the first variable capacitor.
