RF ISOLATION TRANSFRMR The ISOX is an UNUN Unbalanced to Unbalanced Isolation transformer. It's designed to provide galvanic isolation and inter-coupling of an at least partially unbalanced line and a substantially balanced line having similar line impedances which is capable of passing differential signals over a wide bandwidth while substantially attenuating any common mode signals. This transformer acts as a RF isolator by isolating the signal and ground path between two segments of a RF circuit. It provides a means of eliminating the noise developed due to ground currents and pickup over long cable runs.
