Abstract
The usefulness of a temperature-stable microwave resonator is well known. The most common approach in the past to the fabrication of such a device has been to use a relatively low expansion material, such as invar, in combination with higher expansion materials for compensation. Stabilities on the order of 5 parts in 107/°C have been achieved by this method; however, the compensation frequently degrades with age. This article describes a cavity constructed from a glass-ceramic substrate without compensation and having a stability of 1.25 parts in 108/°C from 20°C to 80°C. The method of fabrication is presented as well as a detailed analysis of the known factors affecting resonator stability.Keywords
