摘要： Embodiments provide a novel fabrication method and structure for reducing structural weight in radio frequency cavity filters and novel filter structure. The novel filter structure is fabricated by electroplating the required structure over a mold. The electrodeposited composite layer may be formed by several layers of metal or metal alloys with compensating thermal expansion coefficients. The first or the top layer is a high conductivity material or compound such as silver having a thickness of several times the skin-depth at the intended frequency of operation. The top layer provides the vital low loss performance and high Q-factor required for such filter structures while the subsequent compound layers provide the mechanical strength.

摘要： Various exemplary embodiments relate to a support assembly for a planar filter. The assembly includes a u-shaped housing with angled surfaces at the inner corners of the u-shape, a first dielectric plate having a first angled surface in contact with one of the angled surfaces of the housing, a second dielectric plate having a second angled surface in contact with the other angled surface of the housing, at least one compressible ring, and a cover. The planar filter is supported between the first dielectric plate and the second dielectric plate. The cover compresses the compressible ring to apply downward force on the first and second dielectric plates. The downward force is translated to an inward force by the angled surfaces of the housing. The angled surfaces of the housing apply an inward force on the first dielectric plate and the second dielectric plate.

摘要： A resonator in the Swiss-roll structure, method of making the resonator structure and the system employing the resonator are disclosed. The resonator includes a plurality of layers, including a ceramic layer and a metallic layer. The ceramic and metallic layers are configured in a Swiss-roll form such that the neighboring ceramic layers are separated by the metallic layer. Further, the ceramic layer includes materials that have a dielectric constant of at least about 10 and dielectric loss tangent less than about 0.01 in the frequency range of about 1 KHz to about 100 MHz. The method of forming the resonator includes the steps of disposing a metallic layer, depositing a dielectric ceramic layer, and forming a Swiss-roll structure of the metallic and ceramic layers. Alternate method includes swaging the dielectric material filled metal tubes and forming into Swiss-rolls. Further steps include heat treating the resultant Swiss-roll structure in vacuum, inert atmosphere, or reducing atmosphere to form a monolithic Swiss-roll structure, such that the air gap between turns of the Swiss-roll structure is less than about 1 μm.
