  • Patent number: 8587729
    Abstract: The present invention relates to a receiver capable of reducing influence of disturbance waves and capable of receiving analog and digital broadcast signals without interference with a single front end module, without leading to complexity of the configuration. A receiver 10 includes, on a module board 11, a first terrestrial wave tuner 16 and second terrestrial wave tuner 17 which receive broadcast signals of a first frequency band, and a first satellite wave tuner 14 which receives broadcast signals of a second frequency band different from the first frequency band, with the first satellite wave tuner 14 being situated between the first terrestrial wave tuner 16 and the second terrestrial wave tuner 17. The present invention can be applied to receivers receiving broadcast signals of different frequency bands, for example.

  • Patent number: 7373132
    Abstract: A high frequency signal receiver can prevent higher harmonics other than a necessary higher harmonic from being subjected to frequency conversion so as to interfere with the base band signal in a broadcasting channel frequency band. The receiver has a high frequency signal receiving circuit 1 that comprises an input circuit 3 to which a high frequency signal (RF signal) subjected to frequency conversion from a 12 GHz band to a 1 to 2 GHz band is input, a mixer circuit 4 adapted to frequency convert the signal of 1 to 2 GHz band output from the input circuit 3 into a base band signal, a local oscillation output circuit section 5 adapted to supply a signal of a frequency band to be mixed with the signal output of the input circuit 3 to the mixer circuit 4 and a PLL circuit section 6 to which the source oscillation output signal from the local oscillation output circuit section 5 is input.

  • Patent number: 6307440
    Abstract: In an oscillator circuit employing a pattern coil on a printed-wiring circuit board as a resonator circuit, in order to satisfactorily adjust dispersion in oscillation frequencies, an air-core coil wound by 0.5 turn and less than one turn is provided so as to be connected to the pattern coil in parallel and mounted on the printed-wiring circuit board. The oscillation frequency is adjusted by adjusting the angle of the air-core coil relative to the printed-wiring board.
