摘要： A method for calibrating an analog circuit component comprises the steps of: generating a first signal with a baseband frequency; generating a second signal by processing the first signal via the analog component to be calibrated; generating a third signal by processing the second signal via a power amplifier, wherein the power amplifier operates in a nonlinear region; generating a fourth signal by processing the third signal via a low-pass filter; and defining the adjustment for the In-phase-Quadrature-phase imbalance (IQ imbalance) of the analog component and then re-executing the step of generating the first signal, if the fourth signal shows an IQ imbalance mismatch.
