Patent ID: 6933984

Claim:
A television tuner comprising: an input terminal through which one of UHF band and VHF band television signals are inputted; a UHF tuner which receives the UHF band television signals; and a VHF tuner which is provided together with the UHF tuner and receives at least the VHF band television signals, the UHF tuner comprising: a UHF tuning circuit having a varactor diode and first and second inductance elements serially interconnected and connected in parallel with the varactor diode, where the varactor diode vanes a tuning frequency within a prescribed frequency range in the UHF band; and an impedance circuit serially inserted between an input terminal and a junction of the first and second inductance elements, where an impedance of the impedance circuit increases with increasing frequency in the prescribed frequency range, wherein the impedance circuit comprises a series resonance circuit having a third inductance element and a capacitance element, where a resonance frequency of the series resonance circuit is below a minimum frequency in the prescribed frequency range.
