Abstract
- This paper presents a digitally supported signal injection technique for the intermodulation distortion terms (IMDs) resulting from the non-linearity of Traveling-wave tube amplifiers. It is shown that the state-of-the art analog techniques have inherent limitation due to the inaccuracy of analog components. The proposed technique provides more accurate cancellation of third-order IMD as compared to its analog counterpart. Moreover, it is shown that the presented technique can be easily extended to compensate for higher order IMDs simultaneously. [ABSTRACT FROM PUBLISHER]
