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. Fig. 1.

Excellent amplitude and phase balance are apparent. Note that BAL-0106 is not suitable for baseband data, as any data input will be high pass filtered, particularly on the inverted side. -35 -30 -25 -20 -15 -10 -5 0 0 1 2 3 4 5 6 Return Loss (dB) Frequency (GHz) Common Output 1 Output 2 160 165 170 175 180 185 190 195 200 0 1 2 3 4 5 6 Phase Balance (degree) Frequency (GHz) -50 -40 -30 -20 -10 0 0 1 2 3 4 5 6 Common Mode Rejection (dB) Frequency (GHz) 215 Vineyard Court, Morgan Hill, CA 95037 | Ph: 408.778.4200 | Fax 408.778.4300 | info@markimicrowave.com 05/02/14 BALUN BAL-0106 Page 4 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. 215 Vineyard Court, Morgan Hill, CA 95037 | Ph: 408.778.4200 | Fax 408.778.4300 | info@markimicrowave.com 05/02/14 BALUN BAL-0106 Page 5 215 Vineyard Court, Morgan Hill, CA 95037 | Ph: 408.778.4200 | Fax 408.778.4300 | info@markimicrowave.com 05/02/14 BALUN BAL-0106 Page 6 DC Interface Port Description DC Interface Schematic Common Port / In (Unbalanced) The common port is DC open. Out 1 / 0o Port (Balanced) The 0o port is DC shorted to the 180o port and DC open to ground. Out 2 / 180o Port (Balanced) The 180o port is DC shorted to the 0o port and DC open to ground.
