Abstract
This paper presents the analysis of a wideband low-IF receiver topology based on a quad-IF receiver followed by a Hartley image suppression structure. An equivalent MIMO LTI model is developed. Based on the new equivalent model an architecture to suppress the image leakage caused by the analog mismatch in the I and Q signal paths is proposed. The model-based image suppression is validated through simulation and shown to provide better performance than existing solutions.
