Abstract
A system for adaptively eliminating intermods from a spectrum generated by combining two or more signals in a component or circuit includes a sampler for sampling an output signal of the component or circuit, a signal source for generating a conversion signal having a frequency matched to a target intermod of the spectrum, and a cancellation circuit to generate a cancellation phasor. The cancellation circuit is configured to receive the generated conversion signal and the sampled output signal and generate a cancellation phasor therefrom having a phase and amplitude configured to cancel the target intermod. A combining network can combine the cancellation phasor into the component or circuit to cancel the target intermod from the spectrum.
