Summary:PROBLEM TO BE SOLVED: To provide a signal processing circuit which eliminates separation of signals by switching, and achieves miniaturization, power saving, and circuit simplification. SOLUTION: A first phase shifter and a second phase shifter are provided with functions for converting input signals into signals whose phases are opposite to each other, and the first pass band filter and the second pass band filter are provided with pass band characteristics whose center frequencies are proximate to each other.
