Abstract
A transmitter circuit includes: an in-phase signal processing circuit; a quadrature signal processing circuit; an analog signal processing circuit arranged to operably generate a corresponding analog signal according to the signals outputted from the in-phase signal processing circuit and the quadrature signal processing circuit; a transmitter control circuit arranged to operably control the in-phase signal processing circuit and the quadrature signal processing circuit to cooperate with the analog signal processing circuit to generate a first predetermined signal at a first time point, and to operably control the in-phase signal processing circuit and the quadrature signal processing circuit to cooperate with the analog signal processing circuit to generate a second predetermined signal at a second time point, and an image rejection ratio measurement circuit arranged to operably generate an estimated image rejection ratio of the transmitter circuit.
