Patent ID: 8606116

Claim:
A distortion compensation circuit for compensation of distortion produced by at least one non-linear element in an RF system capable of multiple channel operation modes with different frequency loading conditions resulting from different ranges of frequencies of multichannel RF signals received by the distortion compensation circuit during different respective multiple channel operation modes, the distortion compensation circuit comprising: a frequency detector circuit for detecting a frequency loading condition of a multichannel RF signal; and at least one compensating distortion generator circuit configured to generate intermodulation distortion products from the multichannel RF signal, wherein the distortion generator circuit is configured to generate intermodulation distortion products for different frequency loading conditions, and wherein the distortion generator circuit is configured to adjust generation of intermodulation distortion products responsive, at least in part, to detecting the frequency loading condition such that the intermodulation distortion products are capable of compensating for distortion produced by the non-linear element in the RF system in each of the channel operation modes.
