  • Patent number: 11265026
    Abstract: Disclosed is a tuner device including an input terminal, a separator, a first amplifier, a second amplifier, and a tuner. The input terminal receives an input of a reception signal of satellite digital broadcasts. The separator is connected to the input terminal and adapted to frequency-separate a first signal and a second signal. The first signal is in a low-frequency domain of the reception signal, and the second signal is in a high-frequency domain of the reception signal. The first and second amplifiers respectively amplify the first and second signals. The tuner receives an input of output signals from the first and second amplifiers.
