An image rejection down conversion mixer architecture

An image rejection down-conversion mixer architecture is presented which does not require low-pass filters. The image rejection performance of conventional architectures, the Hartley and Weaver, are analyzed as a function of phase and gain mismatches and compared with the proposed architecture. The proposed architecture that adopts a double poly-phase filter at the front and back of mixer shows better performance due to the inherent compensation characteristics for the mismatch signal.
