Abstract
The present invention provides a local oscillator (LO) leakage controller for use with a receiver. In one embodiment, the LO leakage controller includes a comparison unit configured to process an LO leakage error signal from the receiver to provide a leakage cancellation signal. Additionally, the LO leakage controller also includes a leakage counterbalance unit coupled to the comparison unit and configured to adapt the leakage cancellation signal to the receiver to counterbalance LO leakage in the receiver.
