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.
Claims9
A tuner device comprising:
- an input terminal that receives an input of a reception signal of satellite digital broadcasts;
- a separator that is connected to the input terminal, and adapted to frequency-separate a first signal in a low-frequency domain of the reception signal and a second signal in a high-frequency domain of the reception signal;
- a first amplifier and a second amplifier that respectively amplify the first signal and the second signal;
- and
- a tuner that receives an input of output signals from the first and second amplifiers, wherein a twofold-distortion of adjacent channels of the first signal that overlaps with the second signal above 2.22 GHz is prevented.
A tuner device comprising:
- an input terminal that receives an input of a reception signal of satellite digital broadcasts;
- a separator that is connected to the input terminal, and adapted to frequency-separate a first signal in a low-frequency domain of the reception signal and a second signal in a high-frequency domain of the reception signal;
- a first amplifier and a second amplifier that respectively amplify the first signal and the second signal;
- a multiplexer that frequency-separates a fifth signal in a low-frequency domain of an output of the first amplifier, frequency-separates a sixth signal in a high-frequency domain of an output of the second amplifier, and frequency-multiplexes the separated fifth and sixth signals;
- a tuner that receives an input of an output signal from the multiplexer;
- and
- an output terminal that is connected to the multiplexer.
