Abstract
A Weaver-type ultra-high precision image rejection RF mixer architecture composed of analogue RF and digital IF mixers is proposed, along with the error compensating algorithm for various gain and phase mismatches. A prototype 2.4 GHz image rejection mixer using this technique with an image rejection ratio >70 dB is demonstrated
