摘要：
This article introduces a design method of a C-band Chebyshev band pass cavity filter. The filter is based on the Chebyshev polynomial to achieve an eighth-order bandpass filter with two transmission zeros. This bandpass filter has a center frequency of 3.95GHz and a bandwidth of 500MHz. The in-band return loss is less than -13dB. The out-of-band insertion loss at 3.5GHz and 4.5GHz frequencies are both less than -60dB. This filter is suitable for satellite communication due to its small size. The structure is designed and analyzed by using ANSYS HFSS, and the final simulation results meet the design requirements.
