Comparison of equivalent source match measurements of a 40 GHz power splitter using scalar and vector network analyzers

This paper describes a procedure to measure the equivalent source match of a 40 GHz power splitter using a vector network analyzer. A detailed procedure based on the method proposed by Shimaoka is described. An uncertainty budget of this measurement setup is also developed. We then determine the metrological compatibility by comparing the data derived from two different VNA models to a reference measurement reported by the National Institute of Standards and Technology. A good agreement is confirmed.
