For example; given s-parameters for a transmission line of a 10" length can the matrix be split into two 5" lengths. Assume that the passive s-parameter obeys reciprocity. The reason I'm asking is that I have a test fixture on each end of my measurement that I'm trying to de-embed. The insertion loss can be subtracted very easily, but the return loss and other parameters have a great deal of error dealing with de-embedding from one side of the DUT only. I'm hoping to break the fixture into two equal parts without having a direct point of measurement to do so otherwise. Merrick M.
