    摘要: An embodiment of the present invention further provides an apparatus capable of reducing selected signal components in a communication link comprising a signal line conveying a communication signal including a desired signal component and at least one undesired signal component; a first signal loop coupled to the first signal line capable of generating a signal such that when combined with the first signal line reduces a first of the at least one undesired signal components; and a second signal loop coupled to the first signal line capable of generating a signal such that when combined with the first signal line reduces a second of the at least one undesired signal components. The first signal loop may include a tunable delay enabling the generation of the signal that when combined with the first signal line reduces a first of the at least one undesired signal components. Further, the second signal loop may include a tunable delay enabling the generation of the signal that when combined with the first signal line reduces a second of the at least one undesired signal components. The first of the at least one undesired signal components may be intermodulation distortion and the adding of a signal generated by the first signal loop may reduce or eliminate it. Further, a second of the at least one undesired signal components may be receive signal distortion and the adding of a signal generated by the second signal loop may reduce or eliminate it.
