Analysis of the behaviours of phase and amplitude mismatch compensators to achieve 82.5 dB image rejection ratio

This article presents an experiment to analyse the behaviour of phase and amplitude mismatch compensators in quadrature receivers. The experiment shows that the input signal level and convergence time affect image rejection ratio (IRR) and signal to noise and distortion ration (SNDR). Based on the f...
