  • Abstract
    In this paper, the effect of mismatch in the front-end section of the low intermediate-frequency (IF) receiver is investigated. In particular, the I/Q imbalance in quadrature mixing and component mismatch in complex filtering are concurrently taken into consideration. It is shown that the signal to interference ratio of the low-IF receiver cannot be generally improved by increasing the order of complex filter.
