METHOD OF MANUFACTURING COMPONENT FOR RF FILTER, COMPONENT, AND RF FILTER

摘要

The invention relates to a method of manufacturing a component for an RF filter, to a component for an RF filter, and to an RF filter. The method comprises forming from a sheet metal piece a component (TL, B, T) comprising an edge (ED1, ED2, TLE, HC1, HC2, HES) in the component. In the invention, in order to reduce intermodulation problems, the edge of the component is treated by etching.
