Vector Mixer Measurements with a VNA

As the demand for high frequency applications increases, RF components such as mixers and filters play a critical role in most RF system design. The vector mixer calibration method allows for measurement of mixer transmission complex S-parameters including phase and group delay of the transmission coefficient. The vector mixer calibration method ensures a matching frequency at both test ports of the analyzer, in normal operation mode. The vector mixer calibration procedure will be outlined in this app note.
