摘要：Devices are described which incorporate dielectric material with unusually low (and sometimes negative) temperature coefficient of dielectric constant. Such materials make possible the fabrication of microwave devices which remain stable with changing temperature. This is particularly useful for stabilization of frequency in microwave sources. Stabilization results from the incorporation of small amounts of tin in ceramic material containing mostly Ba.sub.2 Ti.sub.9 O.sub.20.
