NOTE #1: If the DC voltage of the balanced or unbalanced ports is non-zero, DC blocks are required. The balanced ports (2 and 3) are DC shorted.

NOTE #2: To achieve maximum amplitude match to the specified frequency, our baluns are designed to require highly-accurate (< 1%) 50 Ω terminations on the differential outputs.
