Experimental verification of a harmonic-rejection mixing concept using blind interference canceling

This paper presents the first practical experiments on a harmonic rejection downconverter, which offers up to 75 dB of harmonic rejection, without an RF filter. The downconverter uses a two-stage approach; the first stage is an analog multi-path/multi-phase harmonic rejection mixer followed by a second stage providing additional harmonic rejection based on… CONTINUE READING
