<P>PROBLEM TO BE SOLVED: To achieve reduction in the circuit scale and low power consumption of a mixer circuit, capable of eliminating effects of image interruption and harmonic interruption. <P>SOLUTION: Output signals OUTA, OUTB of a second I-side mixer 112I are given to first and second adders 121, 122, respectively. An output signal of a second Q-side mixer 112Q is given to each of the first and the second adders 121, 122. The second I-side mixer 112I and the second Q-side mixer 112Q are shared through an I-side signal path and a Q-side signal path in this way. <P>COPYRIGHT: (C)2013,JPO&INPIT |
