PHASE STABILITY OF TYPICAL NAVY RADIO FREQUENCY COAXIAL CABLES
Abstract
Many of the present military installations utilize highly phase- sensitive electronic systems, of which radio frequency coaxial cables are essential components. It follows that the change in electrical length (the physical length of an air line of equal delay) of the transmission line is an important factor in the coaxial cable design. In phase-sensitive systems temperature variations, bending and flexing, frequency, vibrations, mechanical tension, humidity and equality of physical length are contributing factors affecting phase stability. This paper is mainly concerned with braided coaxial cables and the only factor considered is the variation of electrical length with temperature. Phase stability is defined in this paper as the ability of a cable to maintain a constant velocity of phase propagation throughout a temperature range. (Author)
