<P>PROBLEM TO BE SOLVED: To provide a radio reception apparatus that has an amplifier prior to filter sections and can stably amplify signals within the range of frequencies over which the amplifier can amplify signals. <P>SOLUTION: A radio reception apparatus 1 includes: an amplifier 11 for amplifying a signal received by an antenna 2; a plurality of parallel-connected filter sections 12, 13 connected to the amplifier 11 and provided with frequency bands capable of passing signals within respectively different predetermined ranges of frequencies within the range of frequencies over which the amplifier 11 can amplify signals; and a plurality of tuner sections 14, 15 capable of synchronizing signals passed through the filter sections 12, 13. Cutoff frequencies of the plurality of filter sections 12, 13 are coincident, or a cutoff frequency of one filter section 12 (13) is included in the frequency band of the other adjacent filter section 13 (12). <P>COPYRIGHT: (C)2012,JPO&INPIT |
