Abstract : This report 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 literature 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 switching 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.
