The SY 9223-7637-4 is a balanced-to-unbalanced transformer (abbr. balun) – transforming an unsymmetrical RF signal into a symmetrical one while not transforming the impedance. A bidirectional direction of operation is possible. The SY 9223-7637-4 has a low insertion loss, a wide range of bandwidth and can dissipate a big amount of power. In particular, the balancing transformer SY 9223-7637-4 is intended for transient immunity measurements of pulsed sinusoidal signals (“line-to-line”) according to ISO-7637-4.
