| Abstract: | With the adoption of the small-aperture iris-coupled waveguide resonant cavities,the narrow-band band-pass waveguide filter is designed based on the frequency conversion theory from the low-pass prototype to the band-pass filter.The filter is optimized through the microwave simulation software HFSS with the expressions and charts of the engineering given.The main technical indexes of the filter developed： the insertion loss is less than 0.6 dB within the range of f0±24 MHz,and the attenuation is more than 32 dB beyond the range of f0±145 MHz at band X,which satisfy the demands of realizing the frequency diversity in various radars and microwave communication systems. |
