Direct conversion tuner capable of receiving digital television signals in UHF band and VHF band

A direct conversion tuner includes mixers that orthogonally convert a digital television signal located in high channels of the VHF band and a digital television signal located in a frequency range of 470 MHz to 608 MHz in the UHF band directly into baseband signals, and an oscillator that supplies local oscillation signals to the mixers. The oscillator is caused to oscillate at a frequency that is sixfold a frequency in the high channels of the VHF band or a frequency that is twofold a frequency in the frequency range of 470 MHz to 608 MHz in the UHF band. An oscillation signal having the twofold frequency is divided by two and an oscillation signal having the sixfold frequency is divided by six to generate local oscillation signals having orthogonal phases for both of these oscillation signals. The local oscillation signals having the divided frequencies are supplied to the mixers.
