摘要：Two different configuration of monolithic ceramic waveguide filters with three different width resonators is described. To increase the gap between fundamental frequency and first spurious, the change of resonator geometry is required. Therefore, three different width resonators are used to spread out the spurious resonances without degrading the performance of a filter. The proposed designs offer 70% improvement in stop band rejection in comparison with uniform width ceramic waveguide filter. Improved out of band performance of two six order filters have been presented in comparison with ceramic waveguide filter.
