Abstract
A method and apparatus are disclosed for mitigating a frequency spur included with a transmitter output signal from a wireless device. For at least some embodiments, the wireless device may include an auxiliary synthesizer to generate a spur cancellation signal to be summed with the transmitter output signal to cancel or reduce the frequency spur. The auxiliary synthesizer may also generate an auxiliary clock signal to demodulate a received communication signal. In some embodiments, the transmitter output signal may be looped back to a receiver of the wireless device to determine whether the frequency spur is reduced below a threshold. Data from the receiver may be used to modify the spur cancellation signal.
