Patent ID: 6842198

Claim:
A TV signal receiving tuner for receiving TV signals by dividing them into a plurality of frequency bands, comprising: a local oscillator which oscillates at a frequency range corresponding to a received TV signal having a predetermined frequency band; a second programmable divider which receives a local oscillation signal of the local oscillator and divides the local oscillation signal; a second mixer which directly receives the local oscillation signal and which mixes the received TV signal and the local oscillation signal and frequency converts the received TV signal into an intermediate-frequency signal having a first frequency; and a third mixer which receives an output of the second programmable divider and which mixes the received TV signal and an output of the second programmable divider and frequency converts the received TV signal into an intermediate-frequency signal having a second frequency, wherein frequency conversion is carried out by the second mixer to receive a TV signal having a first frequency band, and wherein frequency conversion is carried out by the third mixer to receive a TV signal having a frequency band lower than the first frequency band.
