Summary:PROBLEM TO BE SOLVED: To enable low current consumption and low cost and to realize miniaturization of a device by reducing a circuit scale while fully exerting effects of space diversity reception when the space diversity reception using a plurality of antennas is applied. SOLUTION: An adder 119 adds an output I signal of a first image eliminating filter 117 with an output I signal of a second image eliminating filter 118. An adder 120 adds an output Q signal of the first image eliminating filter 117 with an output Q signal of the second image eliminating filter 118. A third image eliminating filter 133 inputs output signals of a first AD converter 127 and a second AD converter 128 to eliminate an unwanted signal. A fourth image eliminating filter 134 inputs output signals of the first AD converter 127 and the second AD converter 128 to eliminate an unwanted signal. COPYRIGHT: (C)2006,JPO&NCIPI
