ABSTRACT:
A coaxial cable isolator includes a stepped diameter tubular outer conductive element and a threaded smaller diameter inner conductive element coaxially aligned therewith to form an interruption. A ceramic structure is positioned in the interruption and includes three ceramic capacitive elements, each having a different temperature coefficient selected to provide a minimum of 3.8 and maximum of 5.0 nanofarads of capacitance over the 0 degree Centigrade to +45 degree Centigrade operating temperature range of the isolator. Two ferrite elements for EMI absorption are sandwiched between the three capacitive elements.
