Vector Mixer Characterization for Image Mixers



Joel Dunsmore, Sean Hubert, Dylan Williams


The vector mixer characterization method first introduced by Dunsmore [1] can be used only for mixers where the Local Oscillator (LO) frequency lies between the RF input and output frequencies. Attempts to use the method for mixers with the LO greater than both the input and output frequencies yield erroneous results. An improved method is described which can properly characterize both types of mixers. A theoretical basis is introduced and experimental results are presented which justify the new method.
