Mixed Mode Scattering Parameters
Mixed mode scattering parameters are used to characterize differential circuits. For baluns, this means that the 0° and 180° ports become a single 100Ω differential port and the common port remains the same 50Ω common port. The two-port s-parameters of the balun are then characterized based on differential (d), common mode (c), or single-ended (s) signals. For example: Sds12 is the single ended to differential reverse isolation of the active balun. Sdc11 is the return loss measured as ratio of differential reflect to common mode incident signal on the input port.
