SYSTEM AND METHOD FOR RF SPUR CANCELLATION |
摘要 |
This disclosure is directed to a wireless device with a suppressor that couples to the aggressor signal of a frequency source to generate a cancelling signal for suppressing spurs resulting from operation of the frequency source. The amplitude and phase delay of the cancelling signal are adjusted to optimize the cancellation of the spur. Preferably, a calibration routine is performed to establish appropriate delay and amplitude values to cancel the spurs occurring at each device gain setting.
