Normally linear components such as coaxial cable connectors in radio frequency systems actually are very slightly nonlinear. Sensitive systems can detect spurious signals produced by these nonlinearities and their operation can be impaired by them. This report offers some theoretical explanation of this phenomena as well as some practical methods of minimizing the nonlinear effects. Two of the most predominant causes of nonlinear effects are electron tunneling through thin oxide layers separating the metallic conductors at conductor junctions and the semiconductor action created at a metal-oxide-metal interface. Basically the thickness of the oxide layer will determine whether tunneling or semiconductor action takes place. Contingent on fabrication processing, another potential source of nonlinear operation can be microdischarge between microcracks in metallic structures.
