Patent ID: 7139039

Claim:
An input circuit of a television tuner comprising: an input terminal to which television signals of VHF and UHF bands are inputted; a VHF tuning circuit connected to said input terminal, said VHF tuning circuit being tunable with a low or high VHF band range; a UHF tuning circuit connected to said input terminal, said UHF tuning circuit being tunable with said UHF band; wherein said VHF tuning circuit has two tuning inductance devices connected in series with each other and having a junction thereof connected to said input terminal, and a first switch diode connected in parallel with said two in series inductance devices said first switch diode being turned OFF at least when tuning is performed with said low VHF band range and being turned ON when tuning is performed with said high VHF band range, said UHF tuning circuit is connected to said input terminal through a second switch diode that is turned ON at least when tuning is performed with said UHF band, and said second switch diode is turned OFF tuning is performed with said low VHF band range.
