Co-calibrated Internal Ports

Co-calibrated ports are used in the interior of a circuit. These ports are often used in conjunction with a circuit simulation tool to connect some type of element into your geometry at a later time outside the Sonnet environment. Co-calibrated internal ports are identified as part of a calibration group with a common ground node connection. When em performs the electromagnetic analysis, the co-calibrated ports within a group are simultaneously de-embedded using a high accuracy de-embedding technique1; thus, coupling between all the ports within a calibration group is removed during de-embedding. This type of port is the most commonly used internal port.
