  • Publication number: 20250007626
    Abstract: The present disclosure discloses a signal transmission apparatus having mismatch calibration mechanism. An input circuit performs input signal processing on a first and a second baseband signals orthogonal to each other and forming a complex number baseband signal to generate an input baseband signal. A frequency up-conversion circuit performs frequency up-conversion on the input baseband signal through two signal processing paths having identical configurations and adds processed results to generate an output RF signal. A feedback circuit performs feedback signal processing on the output RF signal to generate a feedback signal. A calibration calculation circuit sets a compensation parameter to be parameter values and retrieves corresponding feedback values from the feedback signal, so as to solve a mismatch parameter between the two signal processing paths of a function of the feedback signal according to the parameter values and the feedback values.
