ULTRA-STABLE MICROWAVE CAVITY.
Abstract
The report covers the development of stable fundamental microwave sources which derive their frequency stability from resonators made of very low thermal expansion glass and glass-ceramic materials. Three different source configurations at L-, S-, and X-bands were analyzed and constructed. The resonator feedback source was selected as the principal type. Computer optimization of an S-band source circuit of this type resulted in a measured source temperature stability of plus or minus 1.88 x 10 to the minus 7 power parts/C over the -25C to +75C temperature range. This is in substantial agreement with the calculated stability. This source showed a frequency stability plus or minus 9 x 10 to the minus 9 power parts/hour when averaged over a 34-hour period in a constant environment. (Author)
