Frequency hopping filter structure

The utility model discloses a frequency hopping filter structure, belongs to the technical field of filters, and solves the problem of how to improve the efficiency of surface mounting of electronic components, connection of functional circuit boards and function debugging of a frequency hopping filter on the premise of ensuring miniaturization of the frequency hopping filter. One end of the digital control circuit board is connected with the I/O expansion substrate through the first flexible circuit board, and the other end of the digital control circuit board is connected with the filter analog board through the second flexible circuit board; when in use, the frequency hopping filter structure is in a stacked form, so that the size of the frequency hopping filter structure is reduced, and miniaturization of the frequency hopping filter is facilitated; automatic surface mounting and function debugging of electronic components can be integrally carried out in a fully-expanded form, and cost reduction and effi
