Loads The broadband loads are instrument grade 504 terminations that have been optimized for performance up to 6 GHz The rugged internal structure provides for highly repeatable connections A distributed resistive element on sapphire provides excellent stability and return loss Opens and Shorts The opens and shorts are built from parts that are machined tothe current state of the art precision machining The short s inner conductors have a one piece construction common with the shorting plane This construction provides for extremely repeatable connections The female open has a separate piece inner conductor that is made from a low dielectric constant plastic to minimize compensation values Both the opens and shorts are constructed so that the pin depth can be controlled very tightly thereby minimizing phase errors Some of the opens and shorts have offsets The lengths of these offsets are designed so that the difference in phase of their reflection coefficients is approximately 180 degrees at all frequencies 1 2 85032B E General Information Calibration Kit Overview Adapters Like the other devices in the kit the adapters are built to very tight tolerances to provide good broadband performance The adapters utilize a dual beaded connector structure to ensure stable repeatable connections The beads are designed to minimize return loss and are separated far enough so that interaction between the beads is minimized The
