Studies on the Reduction of Intermodulation Generation in Communications Systems

Abstract

Potential means of intermodulation generation in multiplex systems are reviewed and evaluated theoretically. The dominant mechanisms involve non- ohmic junctions and ferromagnetic components. Junctions through aluminum oxide films have been studied experimentally and a possible means of improvement is described. Experimental tests of ferromagnetic components show the need to exclude them entirely from multiplex and high performance systems. With care in the choice and assembly of components, it is concluded that intermodulation signals can be kept to the level of thermal noise in most configurations.
