Abstract
The base band signal processing circuit of the present invention intends to improve both the noise characteristic and the distortion characteristic, and moreover set both the characteristics in a desirable balance. The base band signal processing circuit is configured as follows: the first active low-pass filter and the second active low-pass filter are each formed in the balanced type, the first D/A converter differentially outputs the first base band signals and differentially inputs them to the first active low-pass filter, the second D/A converter differentially outputs the second base band signals and differentially inputs them to the second active low-pass filter, the first active low-pass filter differentially outputs the first base band signals, and the second active low-pass filter differentially outputs the second base band signals.
