| Zusammenfassung: | The invention relates to the technical field of communication, and provides a filter which comprises a cavity, a first circuit board, a second circuit board and a connecting circuit board, the cavity is provided with a first mounting cavity and a second mounting cavity, the first mounting cavity and the second mounting cavity are arranged at an interval, the first circuit board is mounted in the first mounting cavity, and the second circuit board is mounted in the second mounting cavity; the connecting circuit board is in butt joint with the first circuit board and the second circuit board so as to communicate the first circuit board with the second circuit board. According to the filter, the first circuit board and the second circuit board are connected through the connecting circuit board instead of a radio frequency coaxial line, and the two ends of the connecting circuit board are in butt joint with the first circuit board and the second circuit board respectively, so that the connecting circuit board is |
