Design of Components for a 7-16 Precision Calibration Kit Using the High Frequency Structure Simulator

A systematic method to design components of a 7-16 connector type precision short-open-load-thru (SOLT) calibration kit for the wireless industry using the High Frequency Structure Simulator (HFSS) at microwave frequencies is presented. To achieve a better than 60 dB accuracy in the nominal optimized value of each individual feature, only one of the 5° segments of the coaxial structure was used to model the equivalent 2D longitudinal cross-section. The validation process for this simplification, together with the test results on the components using a reference TRL/LRL calibration kit for the microwave measurements, is demonstrated. A better than 1.025 VSWR for the 7mm to 7-16 adapters up to 7.5 GHz is reported.
