Abstract
A millimeter wave LTCC filter includes system ground layers, metallized vias, first and second probes, two adjacent ones of the system ground layers define one closed resonant cavity, each closed resonant cavity is provided with a plurality of metallized vias, and the metallized vias of different closed resonant cavities face right to each other, to form concentric hole structures; an aperture of each first metallized via is equal to an aperture of each fourth metallized via, and is smaller than an aperture of each second metallized via that is equal to an aperture of each third metallized via; one end of the first probe is inserted into the first closed resonant cavity and electrically connected with the first system ground layer, and the second probe is coaxially arranged with the first probe, and is inserted into the fourth closed resonant cavity and electrically connected with the second system ground layer.
