摘要： A digital television broadcast receiving section (100) of a mobile telephone terminal includes an antenna (101), a notch filter (102), a low-pass filter (LPF) (103), a low noise amplifier (LNA) (104), a receiving IC (105), a control section (107), and an input section (108). A passband for digital television broadcast is divided into several parts. The control section (107) switches a characteristic of each of the notch filter (102) and the LPF (103) so as to combine filters appropriate for a low-band channel or a high-band channel. Thus, frequencies in a mobile telephone transmission frequency band of the mobile telephone terminal, and frequencies in a band of other systems, the frequencies in these band being interfering waves, are largely attenuated, and at the same time, frequencies in the passband which is a frequency band for digital television broadcast are allowed to pass with low loss.
