De-Interleaved Subsampling Architecture for Homodyne Receivers

Abstract

Abstract-This paper presents a de-interleaved subsampling receiver architecture suitable for homodyne receivers. The proposed topology requires only a single branch to down-convert and extract the inphase (I) and quadrature (Q) baseband signals. Using a singlebranch receiver eliminates the I/Q mismatch issue of traditional direct down-conversion receivers. The simplicity of the proposed receiver architecture makes it an alternative solution for multi-band and multistandard applications.
