Importing RF Device Models

Multiport Network device, i.e. one-ports, two-ports, three-ports and four-ports, are all modeled based on their frequency-domain S-parameters. Most active and passive RF devices can be modeled as multipart networks. For example, RF diodes can be modeled as one-ports, while RF transistors (BJTs, JFETs, MOSFETs, and MESFETs) can be modeled as two-ports. many semiconductor manufacturers publish S-parameter data sheets for their RF devices. The data sets usually contain S-parameters in Mag/Phase format tabulated as a function of frequency expressed in GHz.
