VCO DEVICE, AND TUNER, BROADCAST RECEIVER AND MOBILE TELEPHONE USING THE DEVICE |
摘要 |
<p>It is intended to provide a VCO apparatus having: a local oscillation signal generation circuit for outputting a local oscillation signal corresponding to a frequency signal of a tuned channel to be received, the frequency signal being included in high frequency signals received by an input terminal, and a mixing circuit for outputting a baseband signal by mixing the high frequency signal and the local oscillation signal, wherein the local oscillation signal generation circuit has an oscillator for oscillating the local oscillation signal and a frequency reduction unit for outputting a frequency of the local oscillation signal oscillated by the oscillator to the mixing circuit at a ratio of ×1/N, and the local oscillation signal frequency is set to a frequency different from a communication wireless frequency used by a mobile phone by adjusting the ratio of ×1/N.</p> |
