Abstract
A TE011 cavity filter assembly is disclosed. The system includes at least one resonator operating in TE011 mode having a resonant frequency. The at least one resonator may include a cavity comprising an inner diameter and a cavity length. The at least one resonator may also include a first metal disc inside the cavity. The first metal disc may include a disc diameter and a void in the metal disc, which includes a void diameter and a void depth. The inner diameter of the cavity may be greater than the disc diameter creating a gap with a gap width and a gap depth. The TE011 cavity filter assembly may further include positive coupling.

- wherein at least one of the at least one resonator comprises:
- a cavity comprising an inner diameter, and a cavity length;
- and
- a first metal disc inside the cavity, the first metal disc comprising a disc diameter and a void in the metal disc comprising a void diameter and a void depth;
- wherein the inner diameter of the cavity is greater than the disc diameter creating a gap with a gap width and a gap depth.
A method for coupling two resonator cavities having a resonant frequency in a TE011 cavity filter assembly, the method comprising:
- providing two resonator cavities;
- and
- coupling the two resonator cavities using a long iris,
- wherein the long iris is an aperture having a width, a thickness, and a length, wherein the length of the long iris is greater than half of the free space wavelength of the resonant frequency;
- wherein the two coupled resonator cavities comprise two resonance modes having an odd mode frequency greater than an even mode frequency;
