Abstract
An embodiment filter including metallic plating unitarily forming a spherical shell and a resonator, the resonator defining a resonator cavity, a tuning nut disposed in a lower portion of the resonator cavity, and a tuning screw threadably secured within the resonator cavity by the tuning nut, the tuning screw rotatable to deform an upper portion of the resonator to tune the filter.
Claims10
A filter, comprising:
- a spherical shell;
- a resonator, wherein the resonator defines a resonator cavity, and the spherical shell and the resonator are integrally formed with each other to produce a single structure comprising a single metallic plate;
- a tuning nut disposed within the resonator cavity;
- and
- a tuning screw threadably secured within the resonator cavity by the tuning nut, the tuning screw rotatable to deform an upper portion of the single metallic plate to tune the filter by changing distance between the upper portion of the single metallic plate and the spherical shell.

A filter, comprising:
- a resonator having a cavity extending through an arcuate upper portion of the resonator;
- a spherical shell formed around the resonator;
- the spherical shell and the resonator are integrally formed with each other to produce a single structure comprising a single metallic plate;
- a tuning nut mounted on the spherical shell proximate to the cavity in the resonator;
- and
- a tuning screw threadably secured within the cavity by the tuning nut and the tuning screw being in contact with an upper portion of the single metallic plate, the tuning screw rotatable to change a capacitance between the single metallic plate and the spherical shell to tune the filter by changing distance between the upper portion of the single metallic plate and the spherical shell.
