CERAMIC I-F TRANSFORMERS
Abstract
An improved package for miniature radial resonators and filters in the 1.5 to 5 mc range utilizes a slot design in the micro-module configuration. Slot compartments for the resonators and all electrical interconnections are contained on or within the micro-module body wafer. The resonators can then be inserted and the assembly tested before the cover plates are attached. Three and five element filter sections, as well as single resonators, were satisfactorily packaged in this manner. The contribution of fringing electric fields to the range of action for dot electrodes on a ceramic wafer was determined graphically. The application of photoetching techniques to obtain electrode configurations on ceramic wafers was investigated for electroless nickel, copper, and silver films. Of these, the most desirable appears to be electroless copper, which has adequate adhesion and yields sharp well defined photo-etched images. (Author)
