Abstract
A coaxial resonator of modular construction, wherein the resonator is formed from two or more blocks, or modules, that are fastened to each other. Conductively plated surfaces of the modules may form the center conductor and at least part of the shield of the resonator. A dielectric layer is formed at least partially from the module material, typically ceramic. The module blocks are advantageously made by being cut from ceramic substrate. A resonator, or filter including at least one resonator, can be manufactured without special tools, and may be fabricated by manually assembling modules or by using automatic assembly methods, such as by known printed circuit board assembly techniques.
