Abstract: The paper describes a technique for measuring gain and phase imbalance, DC offset in RF quadrature modulators. The method uses a signal source analyzer for correction carrier leakage and power of undesired sideband. The experimental data is obtained, measurement speed and accuracy are analyzed.
Keywords: quadrature modulator, calibration, gain imbalance, phase imbalance, evm
