Abstract :
A new design of a 14-GHz narrowband bandpass low-loss high-power waveguide filter is described. The design incorporates circular waveguide dual TE/sub 113/ mode Invar cavities for thermal stability and copper thick irises for dissipated heat removal. Experimental results on the filter are presented which show excellent electrical performance under high-power conditions (up to 400 watts). Under higher-power conditions, the temperature rise of the new design is an order of magnitude less than that for a similar all-Invar filter.
