A Novel Gain, Phase and Offset Calibration Scheme for Wideband Direct-Conversion Transmitters


Conventional direct conversion architecture for an RF transmitter is characterized by a single up-conversion stage using high frequency quadrature modulator. The architecture is however very sensitive to quadrature gain imbalance, phase skew and dc offsets in signal path. In this paper, a simple yet highly effective novel automatic calibration scheme is… (More)
