Double-side direct contact calibration thru kit with non-exchanging structure

In this paper, novel microwave double-side calibration and measurement technology is presented. The thru kit which is the key element in the SOLT (Short, Open, Load, Thru) calibration method will be modified into the novel double-side thru calibration kit. And through novel double-side calibration kit, that can accomplishment the GSSG to GSSG four port calibration. For this purpose, there are two different types double-side thru kits which are made with non-exchanging structure one is called the paralleled, the other is called the diagonal.
