Oscilloscope measurements of the BALH-0003 with a 5 Gb/s PRBS pattern. Bit pattern is measured with a 27 -1 PRBS input demonstrating extremely good pulse fidelity for both inverted and non-inverted output. Eye diagrams are taken with a 231 -1 PRBS input demonstrating minimal eye distortion/closure afforded by the extremely low frequency operation of the balun (<200 kHz). 180° 0° 180° 0° INPUT PATTERN DATA INVERTED DATA INPUT EYE DATA INVERTED DATA 215 Vineyard Court, Morgan Hill, CA 95037 | Ph: 408.778.4200 | Fax 408.778.4300 | info@markimicrowave.com Copyright © 2019 Marki Microwave, Inc. | Rev. B HIGH POWER BALUN (200 kHz to 3 GHz) BALH-0003 Page 3 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. Fig. 2. Common to output port insertion loss and output to output port Isolation. Fig. 4. Amplitude balance between output ports. Fig. 3. Return loss for common port and output ports. Fig. 5. Phase balance between output ports. Fig. 6.

B HIGH POWER BALUN (200 kHz to 3 GHz) BALH-0003 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 Copyright © 2019 Marki Microwave, Inc. | Rev.
