Abstract
An intermodulation distortion canceller for use in multi-carrier transmitters is disclosed. In an exemplary embodiment, an apparatus includes a first transmit chain that transmits a first RF signal, a second transmit chain that transmits a second RF signal, and a canceller that outputs a first leakage cancellation signal that is input to the second transmit chain, and outputs a second leakage cancellation signal that is input to the first transmit chain, the canceller generates the first and second leakage cancellation signals from the first and second RF signals or from first and second baseband signals used to generate the first and second RF signals.
