Abstract
Describes the results of a detailed study into the development of an EHF STACOM payload frequency-hopping synthesizer. The synthesizer is required to provide an output between 20.2 GHz and 21.2 GHz, in steps of up to 200 Hz, with a switching time of less than 900 nanoseconds. A litertature review of the various synthesizer architectures was conducted and used to devise three possible synthesizer solutions. These three solutions were then compared on the basis of a number of key criteria. The preferred synthesizer, of the three, will provide the required output in steps of 0.92 Hz, with a swsitching time of 100 nanoseconds. The various characteristics of the preferred synthesizer are described in detail. The viability of implementing a design using the preferred synthesizer approach is discussed. Finally, a specification sensitivity analysis of the selected synthesizer approach is performed.
