Author:De Witt, JJ; Van Rooyen, GJDate:May 2009Although the quadrature mixing radio front-end offers an attractive way to perform frequency translation, its image-rejection capability is severely affected by the gain and phase imbalances (I/Q imbalances) between its two analog signal ...Read more
Author:De Witt, JJ; Van Rooyen, GJDate:Sep 2006Despite the advantages that quadrature mixing offers to radio front-ends, its practical use has been limited due to its sensitivity towards gain and phase mismatches between its in-phase and quadrature channels. DC offsets are also a problem ...Read more
Author:De Witt, JJ; Van Rooyen, GJDate:Jan 2008A quadrature mixing front-end is well-suited toward software define radio (SDR) applications, due to its low complexity and the inherent flexibility that it affords the radio front-end. Its performance is, however, severely affected by gain ...Read more
