Abstract: A filter comprising a cavity, a circuit board located in the cavity, and a filter branch is provided. A power divider circuit is disposed on the circuit board, and includes an input end, a main feeder, and an output end, wherein both the input end and the output end are electrically connected to the main feeder, and the main feeder transmits a signal that is input at the input end and is output at the output end. The filter branch includes a first interface and a first filter line, wherein the first interface is disposed at an opening of the cavity, the first filter line is located outside the cavity, the first filter line is electrically connected to the first interface, and the first interface is electrically connected to the main feeder. The first filter line in the filter branch is disposed outside the cavity.
