<P>PROBLEM TO BE SOLVED: To provide a technique which has been in demand for converting an RF signal of a plurality of operating bands to an IF signal without causing interference in a receiving device which performs carrier aggregation to receive the RF signal. <P>SOLUTION: A receiving device comprises: receiving means for receiving an RF signal of a plurality of operating bands; prime number storage means for storing a plurality of prime number values; division ratio determining means for determining a division ratio from among the prime numbers stored in the prime number storage means; a plurality of local signal oscillation means for oscillating local signals at the division ratio determined by the division ratio determination means; synthesizing means for generating a synthesized local signal by synthesizing the respective local signals oscillated respectively from the plurality of local signal oscillation means; and frequency conversion means for converting the RF signal to an IF signal using the synthesized local signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
