Abstract

Abstract : Research was continued towards the development of ferroelectric ceramic filters, intermediate frequency transformers, and networks. Energy trapping is proposed as an explanation for the behavior of high frequency AT-cut quartz resonators. Energy trapping gives a theoretical basis for the high Q sub m observed for quartz resonators mounted on low Q supports and for the low inter-resonator coupling observed for multiresonator wafers. Measurements in support of the energy trapping theory have been obtained with AT-cut quartz wafers by measuring inter-resonator coupling and the coupling between resonator and an absorbing edge of the wafer. Some improvement has been obtained in piezoelectric ceramic thickness resonators by using hot-pressing fabrication techniques. Results are discussed for three ceramic fabrication techniques.
