Abstract
Bulk acoustic resonators offer Q´s greater than are available by any other means for microwave frequencies. The use of separate resonant substrates and transducers allow higher Q media not available when excitation is by means of the piezoelectricity of the substrate. Resonators with Q´s to 20,000 have been tested. Analysis of temperature propagation characteristics for high Q materials is reported with examples illustrated. Diamond appears to be a candidate for low temperature sensitivity.
