Time Domain Performance Plots
Oscilloscope measurements of the BAL-0003 with a 2.5 Gb/s PBRS pattern. Bit pattern is measured with a 27-1 PBRS input demonstrating extremely good pulse fidelity for both inverted and non-inverted output. Eye diagrams are taken with 231-1 PBRS input demonstrating minimal eye distortion/closure afforded by the extremely low frequency operation of the balun (<200 kHz).

Typical Performance Scattering Parameters
Three port scattering parameters measured as three single-ended 50Ω ports showing relationship between any two ports. For example: S21 and S31, often referred to as insertion loss of a balun, is the output response on ports 2 and 3 with an input stimulus on port 1.

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: S12ds is the differential output response given a single ended input.
