Abstract

The inherent non-linearity of mixers in communication systems creates numerous undesired effects, which are particularly acute in broadband receiver design for software defined radio (SDR) applications. In this paper, previously investigated mixer linearisation techniques are summarised, and a new technique using frequency retranslation is presented. To the author’s knowledge, this linearisation technique is new. Two-tone-test results show up to 33dB reduction in the distortion products and a π/4-DQPSK modulated carrier yield 22dB suppression of adjacent channel interference (ACI)
