    Abstract: A receiver includes a first local oscillator (LO), with a pair of in-phase and quadrature (IQ) mixers coupled to the first LO and configured to generate complex IQ signals having an IQ imbalance. The receiver also includes a second LO, with a complex mixer coupled to the second LO and configured to mix the complex IQ signals and generate intermediate frequency (IF) signals based thereon. A controller is coupled between the pair of IQ mixers and the complex mixer and configured to set the first LO and the second LO so that the complex IQ signals and an interfering signal generated due to the IQ imbalance of the complex IQ signals have a same sign and non-overlapping bands at an input of the complex mixer.
