Abstract:
The present invention provides filter assemblies, tuning elements and a method of tuning a filter. A filter assembly includes a housing having a top cover, a bottom cover and at least one sidewall, the top cover, the bottom cover and the at least one sidewall defining an internal cavity, the housing configured to receive first through third radio frequency ("RF") transmission lines; a top metal sheet mounted within the internal cavity that has a plurality of openings that form a first hole pattern; and a bottom metal sheet mounted within the internal cavity that has a plurality of openings that form a second hole pattern. The top and bottom metal sheets are vertically spaced-apart from each other in a vertically stacked relationship within the internal cavity. The top metal sheet and the bottom metal sheet each include at least one resonator.
Abstract:
The invention discloses a filter component, a tuning component and a method of tuning a filter. The filter component comprises a shell, a top metal sheet and a bottom metal sheet, wherein the shell possesses a top cover, a bottom cover and at least one side wall; the top cover, the bottom cover and the at least one side wall limit an inner cavity; the shell is configured to receive first to third radio frequency (RF) transmission lines; the top metal sheet is installed in the inner cavity and possesses a plurality of openings forming a first hole graph; the bottom metal sheet is installed in the inner cavity and possesses a plurality of openings forming a second hole graph; the top metal sheet and the bottom metal sheet are vertically arranged with an interval as a vertical stack relation in the inner cavity; and each of the top metal sheet and the bottom metal sheet includes at least one resonator.
