Abstract
A ceramic resonator radio frequency filter includes a printed circuit board, one or more first coaxial resonators disposed on the printed circuit board, and one or more second coaxial resonators disposed over the one or more first coaxial resonators so that the one or more first coaxial resonators and one or more second coaxial resonators are arranged in a stacked configuration. The one or more first coaxial resonators and second coaxial resonators electrically connected to the printed circuit board.

(canceled)
A ceramic resonator radio frequency filter comprising:
- a first plurality of coaxial resonators arranged in a first row, each of the first plurality of coaxial resonators extending axially in a first direction;
- a second plurality of coaxial resonators arranged in a second row, each of the second plurality of coaxial resonators extending axially in the first direction, the second row disposed over the first row so that the second plurality of coaxial resonators align with the first plurality of coaxial resonators;
- and
- a printed circuit board extending along a plane transverse to the first direction, the first plurality and second plurality of coaxial resonators electrically connected to the printed circuit board.
A radio frequency module including a ceramic resonator filter comprising:
- a ceramic resonator filter including a first plurality of coaxial resonators arranged in a first row, each of the first plurality of coaxial resonators extending axially in a first direction, a second plurality of coaxial resonators arranged in a second row, each of the second plurality of coaxial resonators extending axially in the first direction, the second row disposed over the first row so that the second plurality of coaxial resonators align with the first plurality of coaxial resonators, and a printed circuit board extending along a plane transverse to the first direction, the first plurality and second plurality of coaxial resonators electrically connected to the printed circuit board;
