A simple yet accurate method for characterizing nonreflecting two-port devices

This paper presents a simple yet accurate method for characterizing a nonreflecting two-port device using a network analyzer. The method is so simple that a through connection of two measurement ports and insertion of the device between the ports are what needs to be measured. Also, it is so accurate that influences of systematic errors on the transmission parameters of the device can be completely removed without using any other calibration standards. A well-known result for a length of nonreflecting and reciprocal transmission line is just one of the applications of the method
