Abstract
The filter is provided, which includes a filter body and resonant cavities disposed on the filter body, and further includes an input port and an output port that are disposed on the filter body. At least one of the input port or the output port is connected to a set of additional resonant cavities, and each set of additional resonant cavities includes: a first additional resonant cavity in signal coupling to the input port or the output port, and a second additional resonant cavity in signal coupling to the first additional resonant cavity. In the filter, the two additional resonant cavities and another resonant cavity connected to the input port or the output port are in a form of a straight line, thereby implementing a flexible layout of cavities of the filter. In addition, a coupling structure is simple, costs are low, reliability and batch consistency is good.
