Methods for embedding and de-embedding balanced networks










Image Number 12 for United States Patent #6665628.

Methods are provided for virtually embedding and/or de-embedding balanced four-port networks into/from a device under test (DUT). For the methods, a set of scattering-parameters is acquired for the DUT. Additionally, a respective set of scatter-parameters is acquired for each of the balanced four-port networks to be embedded and/or de-embedded. A transfer-matrix is generating for the DUT based on its scattering parameters. Further, a respective transfer-matrix is generated for each of the networks to be embedded/de-embedded based on its respective set of scattering-parameters. The transfer-matrix for the DUT is then multiplied with the one or more transfer-matrices associated with the balanced four-port networks to be embedded and/or by an inverse of the transfer-matrices associated with the balanced four-port networks to be de-embedded. A composite transfer-matrix is thereby produced. Finally, a set of composite scattering-parameters is then generated based on the composite transfer-matrix. The set of composite scattering-parameters is representative of the DUT with the one or more balanced four-port networks embedded into it and/or the one or more balanced four-port networks de-embedded from it.
