| Zusammenfassung: | The invention provides a filter. The filter comprises a packaging substrate; the first stacking unit comprises at least two first resonator monomer modules which are stacked on the packaging substrate and are connected in series; each second stacking unit comprises a second resonator monomer module and a filling structure, one end of each second resonator monomer module is connected with the corresponding first resonator monomer module in the first stacking unit, the other end of each second resonator monomer module is connected with the packaging substrate, and each filling structure comprises an upper filling module and/or a lower filling module; the upper filling module is arranged above the second resonator monomer module to enable the second stacking unit to be flush with the top of the first stacking unit, and the lower filling module is arranged below the second resonator monomer module to enable the lower filling module and the first resonator monomer module connected with the lower filling module to |
