The performance of quartz resonators is strongly dependent on the method of packaging. The stringent performance requirements imposed by moddern communication and navigation systems has necessitated the development of a family of microcircuit compatible quartz crystal units for which a new flat package configuration, a ceramic material, a new sealing technique, and novel mounting methods will be used. This report discusses the criteria used to arrive at the new package design. The package consists of a frame with a top and bottom lid. The frame is constructed by a multilayer ceramic technique, with buried layer metallization for the electrical connections. The ceramic currently being used is Al2O3 and the feedthrough metallization is tungsten. The package has low capacitance.
