Design of the 2.92mm Coaxial Calibration Kit

It is well known that the vector network analyzer (VNA) needs to be calibrated before it can be used for testing. The calibration accuracy of the VNA mainly relies on calibration methods as well as calibration kit. In this paper, we design a 2.92mm interface standard calibration kit. The calibration kit designed in this paper can be used for the single-port OSM calibration as well as the two-pot SOLT calibration of the VNA with 2.92mm interface. Both simulations and experiments effectively verify the performance of the designed calibration kit. Meanwhile, by comparing the calibration results with R&S ZV Z229 2.92mm calibration kits, the correctness of our design is further explained.
