A compact wideband current shunt

The need remains for wideband shunts in various measurement functions, despite the advent of current measuring devices based on phenomena making use of more than Ohms´ Law. This paper describes a shunt of circular form no more than 6 mm, thick with a bandwidth comparable to standard co-axial structures. The internal construction is such that the signal-carrying conductors exist only in a field-free region, while the current-carrying structure is of simple construction. The form of the shunt makes it particularly suitable for mounting in series with a hockey-puck semiconductor, or in line with a substantial busbar
