The paper considers a waveguide reject dual-mode -shaped cavity operating on TE101 modes. It is shown that this reject cavity exhibits a pseudo-elliptical amplitude-frequency response. A four-order bandstop filter based on cavities of this type is described. The influence of the geometric dimensions of the waveguide reject -shaped cavity on its frequency response is considered. Keywords: dual-mode -shaped cavity, attenuation pole, iris, bandstop filter.
