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
