Television tuner unit having shield housing

Claim 1

A television tuner, comprising: a housing having a plurality of blocks each of which is surrounded by shielding partitions; a first tuner unit disposed in a first one of said blocks, for selectively and alternately receiving (a) television signals of UHF/VHF band or a CATV signal as a first input signal or (b) a satellite broadcast television IF signal as a second input signal, said first tuner unit converting the first input signal into a first intermediate frequency signal having a frequency higher than a frequency of the first input signal and converting the second input signal into a second intermediate frequency signal having a frequency lower than a frequency of the second input signal; a second tuner unit disposed in a second one of said blocks which is not adjacent to said first one of said blocks in which said first tuner unit is disposed, for converting the first intermediate frequency signal into a third intermediate frequency signal having a frequency lower than a frequency of the first intermediate frequency signal; an FM demodulator unit disposed in a third one of said blocks which is located between said first one and said second one of said blocks in which said first and second tuner units are disposed, for demodulating the second intermediate frequency signal; and a coupling means for coupling said first and second tuner units together, said coupling means including a patterned foil of an electrically conductive material adhered on a circuit board which extends through ones of said shielding partitions disposed between said first and second tuner units.
