    Abstract: Certain aspects of the present disclosure provide methods and apparatus for performing quadrature combining and adjusting. One example circuit may include first through fourth mixing circuits. The first mixing circuit may multiply a radio frequency signal with a first local oscillating signal to generate a first frequency converted signal. The second mixing circuit may multiply a radio frequency (RF) signal with a second local oscillating signal, which may be about 90° out of phase with the first local oscillating signal, to generate a second frequency converted signal. The third and fourth mixing circuits may multiply the RF signal with the second and first signals, respectively, to generate third and fourth frequency converted signals, respectively. A first combining circuit may combine the first and third frequency converted signals, and a second combining circuit may combine the second and fourth frequency converted signals.

    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.
