CABLE (DELAY LINE), DISTRIBUTED CONSTANT TYPE, TEMPERATURE AND FREQUENCY STABLE
Abstract
The intrinsic electric stability of RG-65A/U delay cable was investigated and the stability mechanism analyzed. It was found that temperature-dependent changes in the characteristic impedance and time delay can be attributed largely to capacitance variations in the dielectric between inner and outer conductors resulting from expansion and contraction of the cable components. The mechanism of these changes was determined by test and confirmed by theoretical analysis. A special test was developed for the capacitance variation measurements in which the outer conductor of the cable is replaced by conducting water. As a result of the findings of the stability tests, design specifications were established for an improved RG-65A/U cable. (Author)
