2X-Thru De-embedding for Non-2N Even Number Port Network

2N–port de-embedding has been well studied previously by using the higher order modal-based S-parameters. Such idea is successfully validated by using the 2X-Thru de-embedding, as well as the classic TRL. Non-2N even number (such as 6, 10, 12, etc.) port network S-parameters de-embedding is derived and validated in this paper. By inserting a factitious single-ended 2X-Thru before the fixture characterization, the derivation and validation are demonstrated through a 6-port 2X-Thru de-embedding example. After the fixture characterization, the inserted artificially single-ended 2X-Thru will be removed before the step of fixture removing calculation. As the 2X-Thru de-embedding application always has even number of port 2X-Thru fixtures, the idea in this paper extend the 2X-Thru de-embedding to any arbitrary number of port. The derivation and justification are also suitable for other de-embedding algorithms with even number of port.
