Abstract:
1. A high-order harmonic device of a cavity filter, comprising a base and a lid covering said base; wherein said base comprises a through groove connecting an upper and a lower portion of said base; said base has a plurality of output terminals on a surface of sidewalls of said base, each of said plurality of output terminals has a metallic conductor extending into said base; said base has a resonance space formed indented and bent providing said metallic conductors to reach in and connect to said through groove; said resonance space comprises a plurality of chambers; a respective one of a plurality of partitions having a channel formed above is formed on side walls of adjacent ones of the plurality of chambers, each of said partitions has a space indented downwards from a top side; said lid has a plurality of threading holes with female thread formed corresponding to each of said plurality of chambers and each of said partitions; each of said plurality of threading holes provides to thread with a corresponding adjusting element having male thread for a height adjustment; said plurality of adjusting elements respectively comprise a suppressing element positioned corresponding to a resonance element of each of said plurality of chambers and said each of said partitions in order to reduce spaces for a high-order harmonic wave to transmit signals; each of said resonance elements and each of said suppressing elements has a certain distance from a bottom side of a corresponding chamber of said plurality of chambers and each of said partitions.
