Mixer VNA Measurements

By Anritsu Company

Frequency translated devices are key components of any communication system, whether they are up-converters, down-converters or basic mixers. Since their input and output frequencies are different, they require special features and setups for Vector Network Analyzer (VNA) measurements. With the frequency offset capability of today's VNAs, where the source and receiver are independently synthesized, such measurements are possible and require a much less complicated setup. With special calibration techniques, vector error corrected measurements are possible for added accuracy, and absolute phase, as well as group delay information.

This application note will discuss the following Mixer Measurements, giving helpful hints and recommendations. VectorStar VNA specific information will be included in an appendix section at the end.
