PHASE STABILITY IN FREQUENCY MULTIPLIERS
Abstract
Work is described pertaining to phase stability of frequency multipliers with particular emphasis on Class C vacuum-tube frequency multiplier chains. Various sources of phase perturbations were considered and experimental work performed to establish the magnitude of their effects on a practical device. Temperature variation was found to be the most serious source of phase instability. A general discussion of frequency standards is included and the need for frequency multipliers in the translation of a standard frequency is pointed out. Frequency multiplier chains are discussed and the Class C multiplier selected for the major portion of the work because of the simplicity of its design and its general use. Sources of phase perturbation considered include tube noise, temperature variation, and supply-voltage variation. The effects of such sources were determined on an experimental multiplier chain and recommendations were made regarding multiplier chain design. Indications were that frequency errors due to phase perturbations could be held to less than one in 10 to the 11th power with suitable precautions. It is suggested that a similar program on semiconductor multiplier chains would be of interest. (Author)
