摘要: A mixer circuit with improving characteristic of image rejection by compensating mismatch in a spurious (SRM) used transmitter is provided. The according to the present invention comprises an up conversion unit for modulating base-band input signal RF signal, down converting output from estimating means determining compensation value which component minimized, wherein results unit, and using determined means.
