A Calibration Kit for a 5G-FR2 Band Double-Ridged Waveguide

This paper presents a calibration kit designed for a double-ridged waveguide. This custom designed double-ridged waveguide was developed to address the 5G-FR2 standard frequency band of 24 to 53 GHz. It is used as a blindmating interconnect in over-the-air high-volume manufacturing testing of antenna in package devices for 5G-FR2 applications. A TRL calibration kit design is presented together with the measured results obtained with a manufactured prototype of the calibration kit.
