Temperature Effects in Ceramic Resonators Containing Cement Joints
Abstract
A temperature-related performance degradation has been discovered in ceramic stack 33-mode resonators that employ cement joints. This study sought to identify the mechanism that has produced this performance degradation and to determine resonator design improvements that eliminate or limit this degradation. A computer model of a typical ceramic stack resonator has been modified to include cement joints and has been used to simulate resonator in-air performance as a function of ceramic and cement-joint parameters. Experimental tests and initial modeling results indicate that temperature effects in the cement joints are the chief source of the resonator temperature-related performance degradation. The performance improvement that results from increased stress bias on the resonator during cement curing appears to be due to reduced amounts of cement in the joints.
