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 Copyright © 2019 Marki Microwave, Inc. | Rev. c HIGH POWER BALUN (200 kHz to 10 GHz) BALH-0010 Page 5 215 Vineyard Court, Morgan Hill, CA 95037 | Ph: 408.778.4200 | Fax 408.778.4300 | info@markimicrowave.com Copyright © 2019 Marki Microwave, Inc. | Rev. c HIGH POWER BALUN (200 kHz to 10 GHz) BALH-0010 Page 6 DC Interface Port Description DC Interface Schematic Common Port / In (Unbalanced) The common port is DC short to ground.
