The present disclosure relates to a tuner capable of receiving a television broadcasting signal of a wide band having an operating frequency bandwidth of 48 MHz˜1 GHz, wherein the tuner filters a radio frequency (RF) signal outputted from the low noise amplifier using a tunable filter. The tunable filter includes according to an embodiment an inductor and a variable capacitor as passive elements to reject harmonics. The tuner includes a mixer which mixes an output signal of the tunable filter with a local oscillator signal and converts the mixed signal to an In-phase and Quadrature IF signal, where the converted IF signal of I channel and Q channel is processed through an IF signal processor and is converted to an appropriate signal by a demodulator. |
