Abstract
A method of manufacturing a dielectric filter comprises the steps of: forming a dielectric block; depositing a conductor on the side surfaces and the second surface of the dielectric block, and forming a plurality of resonators, forming input and output terminals on the side surface of the dielectric block, and forming conductive patterns on at least a part of the area of the first surface; and depositing a thermosetting resin on the first surface provided with the conductive patterns, and curing the thermosetting resin. The dielectric filter comprising the protection layer on an open surface prevents defects such as a short circuit generated in a trimming step. The interval between the patterns is reduced to less than 0.04 mm, advantageously facilitating miniaturization of the dielectric filter.
