1. A method for de-embedding at least one device whose S-parameters are unknown and including at least one unknown device port from a system having known system S-parameters at least one system port, the system comprising, in addition to the at least one device whose S-parameters are unknown, at least one device whose S-parameters are known and including at least one known device port, at least one connection between the at least one system port and the at least one known device port;

  • comprising the steps of;

    describing the system in accordance with a system description;

    converting the system description and the known S-parameters of the at least one device whose S-parameters are known to a system characteristics matrix; and

    converting the system characteristics matrix and the known system S-parameters to the S-parameters of the at least one device whose S-parameters are unknown.
