Abstract
In the presence of a strong received signal, non-linear radio frequency (RF) front-end components generate distortion products that add interference to a wanted signal. In this paper, an interference suppression technique using frequency retranslation is presented. When the wanted signal level is high, experimental results show a suppression of intermodulation distortion (IMD) by 25 dB. When a small wanted signal is received along with high level interferers, the technique suppresses interferers by 14 dB and in-band interference by more than 18 dB.
