Patent ID: 7158192

Claim:
A television tuner provided with a high frequency amplifier for amplifying inputted television signals; a mixer for subjecting the television signals which have been amplified to frequency conversion into intermediate frequency signals; a SAW filter for selecting, out of the intermediate frequency signals, intra-range intermediate frequency signals emerging in a range within a prescribed intermediate frequency band; and an intermediate frequency amplifier for amplifying the intra-range intermediate frequency signals, wherein wide band detecting means for detecting the intermediate frequency signals inputted to the SAW filter and generating a first AGC voltage is provided to control a gain of the high frequency amplifier with the first AGC voltage, wherein an input end of the SAW filter is grounded via a series resonant circuit, and wherein a resonance frequency of the series resonant circuit is set to a frequency of extra-range intermediate frequency signals emerging outside the range in the intermediate frequency band out of the intermediate frequency signals inputted to the SAW filter.
