Abstract：Coaxial resonator filter has the advantages of low insertion loss， large power capacity， high sideband suppression， remote parasitic passband and convenient debugging. In this paper， a kind of L wave band high-power coaxial resonator filter is introduced， the initial value of the filter is calculated by the formula calculation software， and the HFSS software is used for modeling， simulation and optimization. After testing and verification， all technical indexes and power capacity of the filter meet the requirements.
Key words：L wave band;coaxial resonator filter;high power
