Abstract: A new technique based on reflection measurement for RF mixers measurement is presented. The technique provides accurate and repeatable measurements of mixers that reciprocal and image frequency can be filtered for input match, output match, conversion amplitude, conversion phase, and group delay. Firstly, by analyzing the measurement method, an one-port vector error model is established. Then, S-parameter matrix of the model is derived and the formulas of the mixer performance parameters are given. Finally, experimental results verify the correctness of the method.
