Abstract
A spurious frequency attenuation servo comprises a first signal generated at a first frequency including at least one spur at at least one respective spurious frequency (spur). The signal is filtered by a first fixed filter. A single sideband (SSB) mixer is configured to output a SSB output signal that comprises a difference of frequencies of an output of the first fixed filter mixed with another signal. The SSB output signal includes a direct current component and the spur, and is received by a second fixed filter, which filters out the SSB output signal and outputs the spur. At least one spur attenuation controller is configured to accumulate error after reading an error term in the spur and to keep integrating until the error term is driven to zero. At least one spur killer is configured to remove the spur when the error term is driven to zero.
