  • Integrated tuner for satellite and terrestrial broadcast reception
    Publication number: 20060174283
    Abstract: A satellite and terrestrial broadcast reception integrated tuner of the invention includes a satellite broadcast reception tuner circuit and a terrestrial broadcast reception tuner circuit. The satellite broadcast reception tuner circuit includes a filter circuit that attenuates a signal having a frequency lower than the satellite broadcast reception band and a quadrature detection circuit to which the output of the filter circuit is directly inputted. With this configuration, the interference of the terrestrial broadcast reception tuner circuit with the satellite broadcast reception tuner circuit is reduced.
