The paper introduces a simple error‑correction technique for measuring two‑port transmission parameters. The technique uses only two non‑reflecting transmission lines and avoids solving explicit error coefficients, eliminating the need for a full set of calibration standards. The method is simpler than existing approaches, produces results that agree with the TRL method for a CPW discontinuity, and is particularly useful for well‑matched two‑port devices with negligible reflection parameters.
This letter presents a simple error correction method for two-port transmission parameter measurement. The method requires measuring only two nonreflecting transmission lines instead of a complete set of calibration standards (at least three) for error correction, it does not need an explicit solution of error coefficients. These two features make it simpler than any other methods. Error-corrected measurement results of a CPW discontinuity using the new method and the TRL method are in good agreement. The new method is useful in characterizing well-matched two-port devices or those whose reflection parameters are of little interest.
